Thought depends on the habitual exercise of the speculative faculties; action, on the determination of the will. The one assigns reasons for things, the other puts causes into act. ... Such is the effeminacy of the speculative and philosophical temperament, compared with the promptness and vigour of the practical! ... Reasoners in general are undecided, wavering, and sceptical, or yield at last to the weakest motive as most congenial to their feeble habit of soul.
