Schopenhauer's criticism of Kant's schemata
From Wikipedia, the free encyclopedia
Schopenhauer's criticism of Kant's schemata is part of Schopenhauer's criticism of the Kantian philosophy which was published in 1819. In the appendix to the first volume of his main work, Schopenhauer attempted to assign the psychological cause of Kant's doctrines of the categories and their schemata.

[edit] From pure intuitions to pure concepts
Schopenhauer claimed that Kant had made an important discovery. This was his realization that time and space are known by the human mind (Gemüth) apart from any worldly experience. In fact, they are merely the ways that the mind organizes sensations. Succession is time. Position, shape, and size are space.[1] The pure forms of time and space are the basis of the perceptions that constitute experience of objects in the external world.
According to Schopenhauer's psychological hypothesis, Kant "… aimed at finding for every empirical function of the faculty of knowledge an analogous a priori function … ."[2] Kant's tacit reasoning was similar to the following: "If pure intuition is the foundation of empirical intuition, then pure concepts are the foundation of empirical concepts." From this symmetrical analogy, Kant claimed that the human mind has a pure understanding, just as he had previously claimed that the mind has a pure sensibility. This pure understanding, according to Kant, consists of pure concepts or categories which allow the mind to discursively think about the objects that are intuitively perceived as being arranged in time and space.[3]
[edit] Using intuitions to substantiate concepts
Kant wrote that "In order to demonstrate the reality of our concepts, intuitions are required."[4] Since empirical concepts are derived from perceptions, examples of the intuitive perceptions can be used to verify the concept. Kant asserted that pure concepts, or categories of the understanding, can also be verified by inspecting their intuitions or schemata. "If the concepts are empirical, the intuitions are called examples: if they are pure concepts of the understanding, the intuitions are called schemata."[5] Schopenhauer described the use of examples in the following way:
Thus, since he aimed at finding for every empirical function of the faculty of knowledge an analogous a priori function, he remarked that, between our empirical perceiving and our empirical thinking, carried out in abstract non–perceptible concepts, a connection very frequently, though not always, takes place, since every now and then we attempt to go back from abstract thinking to perceiving. We attempt this, however, merely in order to convince ourselves that our abstract thinking has not strayed far from the safe ground of perception, and has possibly become somewhat high–flown or even a mere idle display of words, much in the same way as, when walking in the dark, we stretch out our hand every now and then to the wall that guides us. We then go back to perception only tentatively and for a moment, by calling up in imagination a perception corresponding to the concept that occupies us at the moment, a perception which yet can never be quite adequate to the concept, but is a mere representative of it for the time being.

[edit] Pure concepts and the pure intuitional form of time
Kant preferred to create arrangements in symmetrical, analogous tables or lists. For Kant, the symmetrical analogues of empirical examples are the a priori schemata. But, in the case of pure concepts and their schemata, how could a reference be made to intuitive perceptions? Schopenhauer declares that concepts a priori "… have not sprung from perception, but come to it from within, in order first to receive a content from it. Therefore they have as yet nothing on which they could look back [for verification].[7] The only intuition that a priori concepts can be referred to is the pure intuitional form of time, according to Kant. Time, the mind's ability to know succession, is the only content of a pure, a priori concept of the understanding, or category. "The schemata," he wrote, "therefore are nothing but determinations of time a priori according to rules … ."[8].
[edit] Kant's use of symmetrical analogy
Schopenhauer's criticism of Kant's schemata was done, according to him, in order to help solve the mystery of Kant's way of philosophizing. He tried to show that "… after the happy discovery of the two forms of intuition or perception a priori (space and time), Kant attempts, under the guidance of analogy, to demonstrate for every determination of our empirical knowledge an analogue a priori, and this finally extends in the schemata even to a mere psychological fact. Here the apparent depth of thought and the difficulty of the discussion merely serve to conceal from the reader the fact that its content remains an entirely undemonstrable and merely arbitrary assumption."[9]
