The following maxims of common human understanding do not properly come in here, as parts of the Critique of Taste, but yet they may serve to elucidate its fundamental propositions. They are: (1) to think for oneself; (2) to put ourselves in thought in the place of everyone else; (3) always to think consistently. The first is the maxim of unprejudiced thought; the second of enlarged thought; the third of consecutive thought. The first is the maxim of a never passive reason. The tendency to such passivity, and therefore to heteronomy of the reason, is called prejudice.... As regards the second maxim of the mind, we are otherwise wont to call him limited (borné, the opposite of enlarged) whose talents attain to no great use (especially as regards intensity). But here we are not speaking of the faculty of cognition, but of the mode of thought which makes a purposive use thereof. However small may be the area or the degree to which a man's natural gifts reach, yet it indicates a man of enlarged thought if he disregards the subjective private conditions of his own judgment, by which so many others are confined, and reflects upon it from a universal standpoint (which he can only determine by placing himself at the standpoint of others). The third maxim, viz. that of consecutive thought, is the most difficult to attain, and can only be attained by the combination of both the former and after the constant observance of them has grown into a habit. We may say that the first of these maxims is the maxim of understanding, the second of judgment, and the third of reason.
