Why Kant is the turning point
Kant was the decisive break with the Enlightenment and the first major step toward postmodernism. Contrary to the Enlightenment account of reason, Kant held that the mind is not a response mechanism but a constitutive mechanism. He held that the mind—and not reality—sets the terms for knowledge. And he held that reality conforms to reason, not vice versa. In the history of philosophy, Kant marks a fundamental shift from objectivity as the standard to subjectivity as the standard.
Wait a minute, a defender of Kant may reply. Kant was hardly opposed to reason. After all, he favored rational consistency and he believed in universal principles. So what is anti-reason about that? The answer is that more fundamental to reason than consistency and universality is a connection to reality. Any thinker who concludes that in principle reason cannot know reality is not fundamentally an advocate of reason. That Kant was in favor of consistency and universality is of derivative and ultimately inconsequential significance. Consistency with no connection to reality is a game based on subjective rules. If the rules of the game have nothing to do with reality, then why should everyone play by the same rules? These were precisely the implications the postmodernists were to draw eventually.
Kant was thus different from previous skeptics and religious apologists. Many earlier skeptics had denied that we can know anything, and many earlier religious apologists had subordinated reason to faith. But earlier skeptics had never been as sweeping in their conclusions. Earlier skeptics would identify particular cognitive operations and raise problems for them. Maybe a given experience is a perceptual illusion—thus undermining our confidence in our perceptual faculties; or maybe it is a dream—thus undermining our confidence in be distinguishing truth from fantasy; or maybe induction is only probabilistic—thus undermining our confidence in our generalizations; and so on. But the conclusion of those skeptical arguments would be merely that we cannot be sure that we are right about the way reality is. We might be, but we cannot guarantee it, the skeptics would conclude. Kant’s point was deeper, arguing that in principle any conclusion reached by any of our faculties must necessarily not be about reality. Any form of cognition, because it must operate a certain way, cannot put us in contact with reality. On principle, because our minds’ faculties are structured in a certain way, we cannot say what reality is. We can only say how our minds have structured the subjective reality we perceive. This thesis had been implicit in the works of some earlier thinkers, including Aristotle’s, but Kant made it explicit and drew the conclusion systematically.
Kant is a landmark in a second respect. Earlier skeptics had, despite their negative conclusions, continued to conceive of truth as correspondence to reality. Kant went a step further and redefined truth on subjective grounds. Given his premises, this makes perfect sense. Truth is an epistemological concept. But if our minds are in principle disconnected from reality, then to speak of truth as an external relationship between mind and reality is nonsense. Truth must be solely an internal relationship of consistency.
With Kant, then, external reality thus drops almost totally out of the picture, and we are trapped inescapably in subjectivity—and that is why Kant is a landmark. Once reason is in principle severed from reality, one then enters a different philosophical universe altogether.
This interpretive point about Kant is crucial and controversial. An analogy may help drive the point home. Suppose a thinker argued the following: “I am an advocate of freedom for women. Options and the power to choose among them are crucial to our human dignity. And I am wholeheartedly an advocate of women’s human dignity. But we must understand that a scope of a woman’s choice is confined to the kitchen. Beyond the kitchen’s door she must not attempt to exercise choice. Within the kitchen, however, she has a whole feast of choices—whether to cook or clean, whether to cook rice or potatoes, whether to decorate in blue or yellow. She is sovereign and autonomous. And the mark of a good woman is a well-organized and tidy kitchen.” No one would mistake such a thinker for an advocate of woman’s freedom. Anyone would point out that there is a whole world beyond the kitchen and that freedom is essentially about exercising choice about defining and creating one’s place in the world as a whole. The key point about Kant, to draw the analogy crudely, is that he prohibits knowledge of anything outside our skulls. He gives reason lots to do within the skull, and he does advocate a well-organized and tidy mind, but this hardly makes him a champion of reason. The point for any advocate of reason is that there is a whole world outside our skulls, and reason is essentially about knowing it.
Kant’s contemporary Moses Mendelssohn was thus prescient in identifying Kant as “the all-destroyer.”[21] Kant did not take all of the steps down to postmodernism, but he did take the decisive one. Of the five major features of Enlightenment reason—objectivity, competence, autonomy, universality, and being an individual faculty—Kant rejects objectivity. Once reason is so severed from reality, the rest is details—details that are worked out over the next two centuries. By the time we get to the postmodernist account, reason is seen not only as subjective, but also as incompetent, highly contingent, relative, and collective. Between Kant and the postmodernists comes the successive abandonment of the rest of reason’s features.

Kant’s problematic from empiricism and rationalism
In addition to his religious concerns, Kant was also grappling with the problems that the empiricists and the rationalists had run into in attempting to develop satisfactory accounts of reason.
For all of their differences, the empiricists and rationalists had agreed with the broadly Enlightenment conception of reason—that human reason is a faculty of the individual, that it is competent to know reality objectively, that it is capable of functioning autonomously and in accordance with universal principles. Reason so conceived underlay their confidence in science, human dignity, and the perfectibility of human institutions.
Of those five features of reason—objectivity, competence, autonomy, universality, and being an individual faculty—Kant concluded that the sad experience of recent philosophy demonstrated that the most fundamental of them, objectivity, must be abandoned. The failures of empiricism and rationalism had shown that objectivity is impossible.
For reason to be objective, it must have contact with reality. The most obvious candidate for such direct contact is sense-perception. On realist accounts, the senses give us our most direct contact with reality, and they thereby provide the material that reason then organizes and integrates into concepts, those concepts in turn becoming integrated into propositions and theories.
If, however, the senses give us only internal representations of objects, then an obstacle is erected between reality and reason. If reason is presented with an internal sensory representation of reality, then it is not aware directly of reality; reality then becomes something to be inferred or hoped for beyond a veil of sense-perception.
Two arguments had traditionally generated the conclusion that we are aware only of internal sensory representations. The first was based on the fact that sense-perception is a causal process. Since it is a causal process, the argument ran, it seems that one’s reason comes to be aware of an internal state at the end of the causal process and not of the external object that initiated the process. The senses, unfortunately, get in the way of our consciousness of reality. The second argument was based on the fact that the features of sense-perception vary from individual to individual and across time for any given individual. One individual sees an object as red while another sees it as gray. An orange tastes sweet—but not after tasting a spoonful of sugar. What then is the real color of the object or the real taste of the orange? It seems that neither can be said to be the real feature. Instead, each sense-perception must be merely a subjective effect, and one’s reason must be aware only of the subjective effect and not the external object.
What both of these arguments have in common is a recognition of the uncontroversial fact that our sense organs have an identity, that they work in specific ways, and that the form in which we experience reality is a function of our sense organs’ identities. And they have in common the crucial and controversial premise that our sense organs’ having an identity means that they become obstacles to direct consciousness of reality. This latter premise was critical for Kant’s analysis.
The empiricists had drawn from this analysis of sense-perception the conclusion that while we must rely on our sense perceptions, we must always be tentative with regard to our confidence in them. From sense-perception we can draw no certain conclusions. The rationalists had drawn the conclusions that sense-experience is useless as a source of significant truths and that for the source of such truths we must look elsewhere.
This brings us to abstract concepts. The empiricists, stressing the experiential source of all of our beliefs, had held that concepts too must be contingent. As based on sense-perception, concepts are two stages removed from reality and so less certain. And as groupings based on our choices, concepts are human artifices, so they and the propositions generated from them can have no necessity or universality ascribed to them.
The rationalists, agreeing that necessary and universal concepts could not be derived from sense-experience—but insisting that we do have necessary and universal knowledge—had concluded that our concepts must have a source somewhere other than in sense-experience. The problematic implication of this was that if concepts did not have their source in sense-experience, then it was hard to see how they could have any application to the sensory realm.
What these two analyses of concepts had in common is the following hard choice. If we think of concepts as telling us something universal and necessary, then we have to think of them as having nothing to do with the world of sense experience; and if we think of concepts as having something to do with the world of sense experience, then we have to abandon the idea of knowing any real universal and necessary truths. In other words, experience and necessity have nothing to do with each other. This premise too was critical for Kant’s analysis.
The rationalists and the empiricists had jointly struck a blow to the Enlightenment confidence in reason. Reason works with concepts. But now we were to accept either that reason’s concepts have little to do with the world of sense experience—in which case, science’s conception of itself as generating universal and necessary truths about the world of sense-experience was in big trouble—or we were to accept that reason’s concepts are merely provisional and contingent groupings of sense-experiences—in which case science’s conception of itself as generating universal and necessary truths about the world of sense-experience was in big trouble.
Thus, by the time of Kant, the Enlightenment philosophers’ account of reason was faltering on two counts. Given their analysis of sense-perception, reason seemed cut off from direct access to reality. And given their analysis of concepts, reason seemed either irrelevant to reality or limited to merely contingent truths.
Kant’s significance in the history of philosophy is that he absorbed the lessons of the rationalists and empiricists and, agreeing with the central assumptions of both sides, transformed radically the terms of the relationship between reason and reality.
