One man learns Mathematics more easily than another, in common language, he has a turn for Mathematics, i e something in his mental conformation answers to that science The Phrenologist shows the bump denoting this aptitude.

And therefore the question resolves itself into this, “What is the work of the Speculative, and what of the Practical, faculty of Reason.” See the description of apetae II. 5.

praxis is here used in its strict and proper meaning.

That is to say, the Will waits upon deliberation in which Reason is the judge; when the decision is pronounced, the Will must act accordingly. The question at issue always is, Is this Good? because the Will is only moved by an impression of Good; the Decision then will be always Aye or No, and the mental hand is put forth to grasp in the former case, and retracted in the later. So far as what must take place in every Moral Action, right or wrong, the Machinery of the mind being supposed uninjured but to constitute a good Moral Choice, i e.. a good Action, the Reason must have said Aye when it ought. The cases of faulty action will be, either when the Machinery is perfect but wrongly directed, as in the case of a deliberate crime, or when the direction given by the Reason is right but the Will does not move in accordance with that direction, in other words, when the Machinery is out of order; as in the case of the [Greek: akrates]—video meliora proboque, Deteriora sequor.
