"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."
