Critique of Judgement by Immanuel Kant Chapter 47 Page 4

Again, artistic skill cannot be communicated; it is imparted to every artist immediately by the hand of nature; and so it dies with him, until nature endows another in the same way, so that he only needs an example in order to put in operation in a similar fashion the talent of which he is conscious.

If now it is a natural gift which must prescribe its rule to art (as beautiful art), of what kind is this rule? It cannot be reduced to a formula and serve as a precept, for then the judgement upon the beautiful would be determinable according to concepts; but the rule must be abstracted from the fact, i.e. from the product, on which others may try their own talent by using it as a model, not to be copied but to be imitated.

How this is possible is hard to
