The Franciscan theologian Bonaventure flourished in the middle of the thirteenth century, eventually serving as Minister General of the Franciscan order and Cardinal of Albano, having first come to prominence in Paris as a lecturer on Peter Lombard’s Sentences. Conscience and Synderesis is a commentary on Lombard’s book.
Following the structure of that book, Bonaventure divides his commentary into two articles, the first on conscience and the second on synderesis. He calls conscience “a certain directive rule of the will,” whereas synderesis “is called the spark of conscience.” Synderesis thus seems to be something like what Aristotle calls the “efficient” or originative cause of conscience, its archē.
He intends to answer three questions about conscience: Is it in the cognitive part of the soul or the affective part? In its origin does it exist by nature or is it acquired? And in its effects “does every conscience obligate?” Or can one rightly refuse to obey it?
There are five arguments for conscience as existing in the cognitive part of the soul. First, Ecclesiastes 7:22 describes conscience as something that knows; in that passage, the prophet observes that a wise man knows that even righteous men have sinned by cursing others. Second, Damascene calls conscience “the law of our understanding,” and Scripture “directly respects the understanding,” presumably in the sense that divine Revelation tells the truth to human souls. The third argument is etymological: the word for knowing, scientia, is built into conscientia. Conscius means awareness of something in a sciens or knower, a person who has experienced a cognition. Fourth, conscience could be right or wrong. Since making a mistake “relates to a habit or act of understanding”—a passion in itself cannot make a mistake, although of course it can be misdirected by a part of the soul that is mistaken—it “seems that conscience resides in a cognitive power.” Finally, cognition acts in certain ways. It reads, judges, directs, witnesses, and argues. These are all rational acts, not (for example) sense perceptions or appetites. “But all these acts are attributed to conscience, for conscience is a book in which we read, conscience judges inwardly, conscience witnesses, conscience argues, and conscience rule and directs.”
There are five arguments for conscience as existing in the affective part of the soul. A passion cognizes nothing; a habit is ingrained, unchanging once established, hence unlike knowledge, which changes readily and substantially. But if conscience is cognitive, and “the cognitive power is concerned with everything,” both action and contemplation, conscience would “extend not only to moral matters but also to things taught in the various disciplines, which is obviously false.” Second, understanding is to the true what affect is to the good. Conscience has to do with the good; it is a matter of agapic love, of caritas. Third, “the law of the flesh fights against the law of the mind”; both are “motive powers,” not cognitive. Conscience has to do with motive, with fighting the good fight, and hence ranges itself “on the side of the affective.” Fourth, conscience can cause remorse, “a certain grief and passion.” Finally, “the pleasant and the painful reside in an affective power; for example, “the damned will be in great pain from the gnawing worm of conscience.”
Bonaventure resolves the question by classifying conscience as a form of cognition, not as cognition simply, in the broadest sense. He begins by remarking that just as the term “understanding” can be understood in three ways—as the power to understand, as a habit, and as a principle that is understood—so “conscience” can be taken “as the thing of which one is aware” (“the law of our understanding,” as an earlier theologian put it), as a habit (“that by which we are aware”), and as “the power to be aware” (a “natural law written in our consciences”). Bonaventure chooses the definition of conscience as a habit, that by which we are aware; this is what the term is “more commonly taken” to mean. By this definition conscience must be “a habit of the cognitive power,” since awareness is a cognitive capacity, not an affect. [1]
However, there are two ways of knowing. There is “speculative” or theoretical knowledge: knowledge of natural laws, for example. And there is practical knowledge, which aims at right action. Aristotle draws this distinction, saying that theoretical and practical understanding are equally matters of cognition, but they have different aims. Theoretical knowledge is knowledge ‘for its own sake,’ aiming only at the satisfaction of the human desire to know. Practical knowledge is knowledge of ‘what to do’; it “dictates and inclines to movement.” An example of theoretical knowledge is ‘Every whole is greater than its part’; an example of practical knowledge is ‘God should be honored.’ The habit of knowledge simply is called scientia; the habit of practical knowledge is called conscientia. Conscience “does not perfect the speculative power in itself but as it is joined in a certain way to affection and activity.”
Therefore, in reply to the five arguments claiming that conscience is not cognitive, Bonaventure says that insofar as conscience is a power it is a power “applied to knowing about conduct or morals.” As a habit, it can be either natural or acquired, and as such it can go right or wrong, either purifying or defiling the soul. Insofar as it is good it “dictates and inclines to good and draws back and flees from evil.” That doesn’t make it “affective,” only that “it has a certain concomitance with will and affection.” And while it is unquestionably true that the law of the flesh is opposed to the law of the mind, the law of the flesh “presupposes a disordered representation of carnal things in fantasy and cognition”; it has a cognitive element, albeit a mistaken one. The remorse we feel after violating conscientious knowledge is of course affective, but that feeling is not itself conscience. Similarly, the painful and pleasurable feelings we experience in response to our thoughts and actions may well be conscientious but are not conscience itself. The conscience testifies and judges, the feelings of remorse or rejoicing follow from those cognitive perceptions.
It might be suggested that the question of conscience as Bonaventure addresses it points the way to a distinction between Christian Aristotelianism and classical philosophy generally. The classical philosophers understand the soul as a natural entity with a firmly established and well-articulated set of characteristics. In the relatively simple description offered by Socrates in Plato’s Republic, the soul has three parts: logos or reason, thumos or spiritedness, and the epithumia or appetites. In Christianity, the human soul proves more malleable. The first human being was made in the image of God, but the image has little of the Original’s firmness. Eve is readily beguiled by the Serpent; as far as the reader can tell, Adam simply goes along with her offer of the forbidden fruit of moral knowledge. Even the chosen nation, Israel, wavers repeatedly between obedience and disobedience to God’s commands. And in the New Testament, the soul appears as a battleground on which much more powerful forces, divine and demonic, struggle for rule. This may explain why in Christian thought, including that of Bonaventura, Socratic thumos is replaced by the will. Spiritedness has a firm object: it loves honor. (In Augustine, closer to Platonism than many Christians, this takes the evil forms of pride and love of domination.) In Christianity, however, the will tends to waver, even before its corruption in the Garden of Eden. Will is ‘free’; it can incline one way or another, depending upon which external spiritual forces seize control of it. Bonaventure’s treatment of conscience as a natural habit as it were borrows some of the solidity of Aristotelian ‘naturalism’ for Christian purposes.
Bonaventure moves next to the question of whether conscience is an innate or an acquired habit. There are six arguments for its innateness. In Romans 2:14-15 the Apostle Paul remarks that gentiles without the divine law are nonetheless “a law unto themselves because they show that the work of the law is written in their hearts, their conscience bearing witness to them.” Scripture itself testifies that “conscience bespeaks a habit naturally inscribed in the human heart.” Augustine concurs; human beings have “a natural judicatory” within them, a standard of conduct. Another Father of the Church, Isidore, teaches that “natural right is that which nature has taught animals,” and if animals have so been taught, “much more has it taught human beings, who excel all animals.” Further, “the cognition of natural right is nothing other than conscience.” Moreover, “we have a natural instinct to seek blessedness and honor” from our parents; since we could not be this way “without some prior cognition,” and conscience is a kind of moral cognition, conscience must be innate. As a consequence of these first four arguments, Bonaventure remarks that since human beings cognize natural law, that cognition must occur “either by acquisition or by nature. If the former, it is similar to “the political virtues.” If by nature, “the cognition of natural law is nothing other than conscience. Finally, “natural right binds the will naturally.” But to be bounded, the will needs to know what it is that it is to do; “understanding precedes affect.” Conscience is the cognition of natural right or law.
Against the claim that conscience is innate, opponents make six arguments of their own. In On the Soul, Aristotle compares “the soul at birth” to a blank tablet with nothing inscribed on it. (By this reading, Aristotle anticipates Locke.) If so, the soul can have “no innate cognition.” Augustine adds a Platonic argument: Yes, the soul has knowledge in it at birth but “burdened by the weight of the body, it forgets the things it used to know.” However, Augustine cites this argument in his Retractions. “He would not retract this unless he held it to be false,” and indeed Augustine did convert from Platonism to Christianity, necessitating exactly this kind of retraction. The opponents’ third argument is more elaborate. To know something complex, we first need to know the simple elements that compose it, the “incomplex.” For example, we can’t know a principle “unless we have cognition of its terms.” So far, this accords with Aristotle’s Posterior Analytics. But—and here again, the opponents come across as proto-Lockean—we know the “incomplexes” only through the senses; no one understands color without sight, and to lose a sense is “necessarily [to] lose knowledge.” Therefore, “all cognition of complexes” too “is necessarily acquired and taken from sense.” Conscience being “a cognition of a complex”—of what Locke calls a complex idea—namely, natural right—conscience must be an acquired habit, not an innate, natural one. Similarly, if conscience aims at practice, at conduct not theory, and “things pertaining to conduct are as difficult or more difficult to know than those pertaining to simple contemplation,” conscience must be an acquired habit, a thing gained from experience not simple sense perception. Sense perceptions, moreover, are infallibly correct, although we may misinterpret them. Since conscience can err, it must be an acquired not a natural habit. Finally, “natural habits are present in everyone and at all times, because those things are natural which are the same for all and which go with a nature inseparably. But consciences are not the same in all,” nor are they present in the same person at all times. The opponents give the example of a person entering a religious order who develops “a conscience that forbids acting against the counsels [of perfection], a conscience one did not have before.” Therefore, conscience is acquired, not natural.
Dismissing the Platonic argument that both Augustine and Aristotle have refuted, Bonaventure isolates “three opinions among the learned about the origin of cognitive habits,” all of which hold that they are both natural and acquired. These opinions “differ, however, in assigning the ways in which these habits are innate and acquired.”
The first formulation distinguishes the “active understanding” or “active intellect” from the “possible understanding” or “possible intellect.” It is the possible understanding that begins as a blank slate, then receives sense impressions, with no assistance from the active understanding. Bonaventure rejects this. If the active understanding has cognitive habits, why would it not “communicate them to the possible understanding without help from the senses”?
The second formulation holds that cognitive habits are innate insofar as the mind perceives universals, acquired insofar as it perceives particulars. A variation of this formulation holds that cognitive habits are innate with regard to principles, “acquired with regard to cognition of conclusions.” This, however, also diverges from Aristotle and Augustine. They both deny the Platonic claim that the mind contains principles innately. On the contrary, “cognition of principles is acquired by way of sense, memory, and experience” (Aristotle) or by means of “a certain unique incorporeal light,” analogous to the way “the fleshly eye sees things in front of it in physical light” thanks to its natural power (Augustine).
Bonaventure endorses the third opinion. For cognition to occur, two things must happen: “the presence of something cognizable and a light by which we make judgement about it.” Thus cognitive habits are innate “by reason of an inwardly given light of the soul,” acquired because the thing cognized has a species or form to be perceived by that inner light. Bonaventure calls this natural light “a natural judicatory.” We “acquire” the external species by means of the senses: How else would I perceive the distinction between a whole and a part if I never saw or heard or tasted or touched a whole thing and one or more of its parts? “On the other hand, that light or natural judicatory directs the soul itself in making judgments both about things that can be cognized and things that can be done.”
Bonaventure adds another distinction. Some cognizable things are “very clearly evident, such as axioms and first principles,” while others are not so clearly evident, such as the conclusion of a geometric proof based on the axioms. The same goes for cognition aimed at practice, for “things that can be done.” It is easy to perceive “Do not do to another what you do not want done to you,” but that cannot tell me what to do if I’m thinking of asking for elective surgery. The innate light of cognition is necessary but not sufficient to reach a scientific conclusion; the same goes for moral conclusions, things “which we are bound to do” that we know not by consulting moral principles but “only through additional instruction.” Hence conscience, which has to do with morality, with choices about actions, is “an innate habit” in one way, “an acquired habit” in another. The “natural light” of conscience “suffices for knowing that parents should be honored and neighbors should not be harmed,” but the species “parent” or “neighbor” doesn’t exist in me prior to sense impressions I acquire from the outside world. The innate, non-sensory cognitions (awareness of God) and the innate, non-sensory “affects” or feelings (love, fear) are what Bonaventure calls “essences.” The awareness of God and of self, love, and fear do not come to us from any acquired cognition through the “outer senses.” This is why Aristotle says that “nothing has been written in the soul”—as Locke claims—not “because there is now awareness in the soul, but because there is no picture or abstracted likeness in it.” Or, as Augustine argues, “God has implanted a natural judicatory in us,” the truth, which “is naturally impressed in the human heart.”
The third question Bonaventure addresses with respect to conscience is “Must we do everything that conscience dictates as necessary for salvation?” Advocates quote Romans 14:23, “Whatever is not of faith is sin,” drawing the conclusion that since whatever is not of faith is against conscience, “we must do everything that comes from a dictate of conscience.” They also say that laws are obligatory, binding; since “conscience if the law of our understanding,” we must obey it. They also argue that “we must do what a judge commands”; “conscience is our judge”; ergo, we must obey it. Finally, that if I do something I believe to be a mortal sin it is indeed a mortal sin because I show “contempt for God” in so acting. “If we cannot not believe what conscience dictates,” we “sin mortally if we act against it.”
Those who deny that we must do everything conscience dictates to receive salvation contend that “conscience sometimes dictates doing something that is against God.” It must then be that our conscience is mistaken, not God, and we should disobey our conscience. Further, “conscience cannot obligate to anything to which God cannot obligate, since conscience is below God.” Acting against God’s law is the true sin, not acting against conscience; “conscience does no in virtue of itself bind anything.” Nor can conscience absolve us from any obligation impressed upon us by God or indeed by any other superior authority.
Bonaventure thinks that some distinctions are in order.
- To what does conscience bind?
- Does it bind to everything it dictates?
- Is a human being “caught in perplexity when conscience dictates one thing and divine law dictates the contrary”?
- To which we owe our obligation, when conscience and “the command of a superior” conflict with one another?
It depends. Sometimes conscience dictates “what is according to God’s law, sometimes what is aside from God’s law, sometimes what is against God’s law.” This doesn’t apply to counsels or persuasions, only commands—laws being one form of command. Conscience of course does bind when we act according to divine law. If conscience tells us to do something that has no relevance to God’s law, we may do it so long as conscience tells us to do it; Bonaventure gives the example of a conscientious urge to pick up a straw. If conscience tells us to act in violation of God’s law, however, conscience is wrong and God is right. In such instances, conscience actually “puts a human being outside the state of salvation” so long as the urge lasts. If we don’t “set conscience aside” we “sin mortally.” The dilemma is that in acting against conscience we involve ourselves in showing contempt for God, “as long as we believe, with conscience so dictating to us, that what we are doing is displeasing to God, although it may be pleasing to God” in fact. This is the point Paul the Apostle makes in Romans 14 in saying that whatever does not proceed from faith is sin.
Why? Because “God attends not only to what we do but to the spirit in which we do it.” If we act against the divine law while our conscience mistakenly tells us we are acting in obedience to it, we act “not in a good but in a bad spirit and because of this” we sin mortally. We should therefore obey the commands of our superiors, as Paul himself tells us to do, respecting the commands of emperors, not only in fear of punishment but in fear of sinning. Conscience “truly is a law but not the supreme law.” At the same time, “whenever we believe we are sinning mortally, we are sinning mortally.” It is only when we knowingly sin against divine law, including the divine law that commands us to obey human superiors, that we sin mortally. “Conscience is like a herald or messenger of God, and it does not command what it says from itself, but it commands, as it were, from God, like a herald proclaiming the edict of a king”; conscience “binds in things that can—in some way—be done well.” In those circumstances in which we “do not know how to judge maters, in that we do not know God’s law, we ought to consult those who are wiser, or, if human counsel is lacking, turn to God in prayer.”
Bonaventure next turns to synderesis, “the spark of conscience.” Should it be classified as cognitive or affective? Can it be extinguished by sin? Can it become depraved through sin?
Four arguments support the claim that synderesis should be classified as affective—a feeling, not a form of knowledge. The Church’s Gloss on Ezekiel 1:10 calls synderesis “the spirit that intercedes for us with sighs too deep for words”—as a profound feeling, not as logos. For his part, Ambrose describes men and women as beings who “naturally will the good” even as they are “subject to sin.” Will is affective, not cognitive; it motivates but it does not know. Since conscience aims at knowing, the spark of conscience, the thing that impels it to action, must be synderesis, not conscience itself. Human sinfulness or corruption stems from sensory motives—finding the apple pleasing to the eye and apparently tasty. This “rational motive part,” the thing that inspires conscience, can be “nothing except synderesis.” Finally, “just as understanding needs light for judging, so affect needs a certain heat and spiritual weight for loving rightly,” a “natural judicatory in the cognitive part of the soul.” This is conscience. In the same way, there needs “a weight in the affective part of the soul directing and inclining good.” That is synderesis.
Four arguments contradict the claim that synderesis should be classified as affective. Jerome maintains that the prophet Malachi’s adjuration to “guard your spirit” and remain faithful to your wife cannot arise from “the animal part” of the soul, which might advise one rather differently, but from the rational part, which Jerome calls synderesis. The Gloss on Luke 10:30 holds that a man’s “sense of reason” cannot be stripped from him even if he is inflicted with a severe beating; since “the sense of reason resides in reason,” and the sense of reason is synderesis, synderesis must be rational. Indeed, if synderesis is the spark of conscience, and conscience is cognitive, why would synderesis not belong to cognition instead of the affective? Finally, synderesis must be a habit by process of elimination. If it were affective, a thing “on the motive side” of the soul, it would be “either a power or a passion or a habit.” It isn’t a passion, since it is not sinful. It isn’t a habit, because a good habit is a virtue, a bad habit a vice, and synderesis is neither a virtue nor a vice. Nor is it a power, because “the power of will is related equally to any object of appetite whatever, including such objects as food and drink. Synderesis is the spark of conscience, not of hunger or thirst. What else can it be, then, but an element of cognition?
More generally, Bonaventure asks, what exactly is synderesis? How is it related to natural law and conscience? How is it related to the three “powers of the soul” identified by Plato’s Socrates: the rational, the “irascible” or thumotic, and the “concupiscible” or appetitive? Is synderesis a fourth part of the soul, “outside and over” these three powers, an eagle soaring above them all? Or is synderesis a part of one of the three powers or ‘parts’ of the soul already identified by the philosopher?
One plausible but inadequate account holds that synderesis is part of the rational part of the soul, the “higher portion,” which turns the soul toward God and is therefore always right, in contrast with the lower portion of the rational part, which turns the soul toward earthly things, toward practice, and is called conscience. Synderesis directs us to the divine law, conscience to the natural law. The problem is that, as already established, reason may err, even to the point of committing a mortal sin. Further, as Jesus commands, we must love not only God but our neighbor, who resides in this world and not yet in Heaven.
According to “another way of speaking, we should understand motivation insofar as guided by reason to consist of two aspects, the way of nature and the way of deliberation—speculation or theory and practice; similarly, “just as free judgment consists of reason and will as they move deliberatively, conscience and synderesis relate to reason and will insofar as they move naturally. Synderesis, conscience and the natural law “always incline to good, “but free judgment “sometimes inclines to good, sometimes to evil. Synderesis is the power; conscience is the habit; natural law inheres in objects. Since conscience is cognitive, either there must be something that directs us to action other than conscience or synderesis, or that synderesis is that thing which so directs us.
Which is it? “There is a third way of speaking”: the understanding “has a light which is a natural judicatory for it, directing the understanding in what is to be known”; affect also has “a certain natural weight directing it in what is to be sought.” The things to be sought are either morally honorable or advantageous. Similarly, cognizable things may be objects of contemplation or those relating to morals. Conscience is the name for the judicatory power that has such a habit, such a way; synderesis is the name for a power “susceptible to habituation rather than a habit.” “Power as thus habituated” urges us toward the morally good, and therefore belongs to the affective side of the soul. When we appeal to God with sighs too deep for words,” we exercise just this affective habit toward the good. Synderesis is the spark of conscience in the sense that “conscience alone,” being cognitive, “can neither move nor sting nor urge except by means of synderesis, which, as it were, urges and ignites.” “Just as reason cannot move except by means of will, so neither can conscience move except by means of synderesis.” Synderesis isn’t “a power of will in general but only will insofar as it moves naturally.”
What, then, is the relation of synderesis to natural law, as distinguished from deliberation, the realm of virtues and vices? Natural law relates to both synderesis and conscience. “We are instructed by natural law and are rightly ordered by it”—that is, the three parts of the soul attain their right order by conforming to nature, to what a human being really is. Natural law is a habit or way including both understanding and affect, conscience and synderesis. “In another sense natural law is called a collection of the precepts of natural right, and in this sense it names the object of synderesis and conscience,” with conscience dictating and synderesis inclining us either to seeking or to refusing. This latter sense Bonaventure considers the more proper meaning of natural law. Synderesis is then “an affective power insofar as it is by nature easily turned to good and tends to good,” whereas conscience is “a habit of practical understanding.” “Natural law, finally, is the object of both.” Synderesis is the word for “the affective power as its motion is natural and right,” indeed flying like an eagle “over the others,” the other parts or powers of the soul, “not mingling with them when they err but correcting them.”
But can synderesis be extinguished by sin? The Gloss on Psalm 14:1 states that some men are “devoid of every rational power.” And if you argue, as Bonaventure does, that synderesis isn’t a rational power, there is the Gloss on Psalm 56:2-3, saying that “foolish arrogance is like a numbness, when someone trusting himself neither fears nor is cautious”—a symptom of “spiritual sickness” occurring when synderesis has been extinguished. Too, “heretics endure death for the sake of their errors without any remorse of conscience,” another sign that synderesis “seems to be entirely extinct in them.” Finally, since sin can be “totally extinguished, as is clear with regard to the Blessed Virgin,” so too “synderesis can be extinguished by a multitude of sins.”
The contrary view hold that the spark of conscience wasn’t extinguished even in Cain, “a great sinner.” Augustine also testifies that there is no shamefulness “so vicious that it makes one lose all sense of what is morally honorable.” Synderesis “is naturally inherent in us,” unalienable; vice “does not destroy the last vestiges of nature.” Finally, even the damned suffer “remorse of conscience,” which can only be ignited by synderesis; indeed, “this remorse is especially intense in them,” one of the worst torments they suffer.
Bonaventure answers that synderesis can be impeded temporarily but not extinguished because “it is something natural” to us. The “vain and fictive joy” of heretics, who “believe that they are dying for the piety of faith when they are dying for the impiety of error; “the wantonness of pleasure” whereby “a human being is sometimes so absorbed by a carnal act that there is no place for remorse” or for reason, either; “the hardness of obstinacy,” seen in those “who are so far confirmed in evil that they can never be inclined to good”: all these conditions of the soul finally earn the rebuke of conscience, sparked by synderesis—a rebuke “especially vigorous in the damned,” for whom it comes too late. The damned retain their human nature, and with it synderesis, now acting in them “as punishment.” Although “synderesis can be impeded in its act yet never universally extinguished, permanently and with respect to every act.” Adam’s fall did not extinguish his humanity, or ours.
But, if not extinguished, can synderesis become depraved through sin? Evidently so, some say, inasmuch as there are “shameless sinners” in whom synderesis has been “overthrown.” The Gloss on Jeremiah 2:16 explains, “A malignant spirit reaches all the way from the lower members to the top of the head when the sickness of defiance corrupts the mind’s chaste height,” which is “synderesis itself.” Since conscience can err, so synderesis must be deviant at such times. Sin can rule the soul at the same time as synderesis remains within it; therefore, synderesis can become depraved through sin.
Those who deny that synderesis can become depraved through sin recall the Biblical comparison of synderesis to an eagle, which soars above the other three parts of the soul, correcting them when they err. Even when I do what I do not want to do (Romans 7:16), synderesis is what tells me I do wrong. “The act of synderesis always reacts against fault, even in the worst sinners,” and so cannot be said to have been depraved, though they are. And finally, we know that even the worst sinners sometimes repent. While there is life there is hope. “But the rightness that adheres most tightly is rightness by way of nature, and this is synderesis”; “therefore, it does not seem that it can become depraved through fault.”
Bonaventure is especially concerned with answering the claim that sin corrupts the highest part of the human mind. The argument claims that “the higher portion of reason has two ways of moving: either as it is turned toward God and is ruled and directed by eternal laws, and, in this way, sin does not exist in it; or insofar as it is turned toward lower powers, and in this way it takes from them occasion for deviation and can become depraved by sin.” He replies that “synderesis of itself always urges to good and reacts against sin.” Sin is a deliberate act of the will, not an act of the will “as it exists by nature or moves naturally.” What happens when we sin is rather like what happens when a good ruler is overthrown by rebels. He is still good, but the rebels overpower him. “For a lord’s presiding depends on two things, namely, the rectitude of the one presiding and the submissiveness of the one serving.” Synderesis “of itself is always right, yet because reason and will frequently hinder it (reason through the blindness of error and will by the obstinacy of impiety) synderesis is said to be overthrown, in that its effect and its presiding over the other deliberative powers is repelled and broken through their resistance.” For its part, conscience “is always right when it stays on the level of the universal and moves in a single direction,” but when it “descends to particulars and makes comparisons it can become erroneous, because here it mingles with the acts of deliberative reason.” Bonaventure gives as his example the adherence of Jews to the laws commanding circumcision and the avoidance of certain foods. They are right in believing “that God should be obeyed,” a prompting of the “natural judicatory” of conscience. They are mistaken, he claims, in those particulars, which are particular applications of that prompting. In this as in all conscientious mistakes, “it is not synderesis” that is “turned aside, although conscience errs.” Another way of putting this is that synderesis is a natural power, naturally habituated. “Nature, taken by itself, always moves rightly.” But conscience is not only a natural but also an acquired habit, and acquired habits “can be either right or deviant in character,” right or erroneous. Free judgment is under synderesis, not the other way around.
Note
- In this, Bonaventure follows Aristotle, Nicomachean Ethics 1094a, where the philosopher writes that “awareness” of the highest good must “have great weight in one’s life,” that is, in our choices and practices.
