The free self-determination which Kant denied to the speculative, he has expressly vindicated for the practical reason. To many minds this particular aspect of the Kantian philosophy made it welcome; and that for good reasons. To estimate rightly what we owe to Kant in the matter, we ought to set before our minds the form of practical philosophy and in particular of 'moral philosophy,' which prevailed in his time. It may be generally described as a system of Eudaemonism, which, when asked what man's chief end ought to be, replied Happiness. And by happiness Eudaemonism understood the satisfaction of the private appetites, wishes and wants of the man: thus raising the contingent and particular into a principle for the will and its actualisation. To this Eudaemonism, which was destitute of stability and consistency, and which left the 'door and gate' wide open for every whim and caprice, Kant opposed the practical reason, and thus emphasised the need for a principle of will which should be universal and lay the same obligation on all. The theoretical reason, as has been made evident in the preceding paragraphs, is identified by Kant with the negative faculty of the infinite; and as it has no positive content of its own, it is restricted to the function of detecting the finitude of experiential knowledge. To the practical reason, on the contrary, he has expressly allowed a positive infinity, by ascribing to the will the power of modifying itself in universal modes, _i.e._ by thought. Such a power the will undoubtedly has: and it is well to remember that man is free only in so far as he possesses it and avails himself of it in his conduct. But a recognition of the existence of this power is not enough and does not avail to tell us what are the contents of the will or practical reason. Hence to say, that a man must make the Good the content of his will, raises the question, what that content is, and what are the means of ascertaining what good is. Nor does one get over the difficulty by the principle that the will must be consistent with itself, or by the precept to do duty for the sake of duty. 55.] (c) The Reflective Power of Judgment is invested by Kant with the function of an Intuitive Understanding. That is to say, whereas the particulars had hitherto appeared, so far as the universal or abstract identity was concerned, adventitious and incapable of being deduced from it, the _Intuitive_ Understanding apprehends the particulars as moulded and formed by the universal itself. Experience presents such universalised particulars in the products of Art and of _organic_ nature.
