Note 21 — Chapter IV
Arthur Brodrick Bullock translation
It is nothing but one and the same will, which at one time is called sensuous desire, when it is stimulated by acts of judgment, formed in consequence of perceptions of the senses; and which at another time is called rational desire (i.e. desire of the reason), when the mind forms acts of judgment about its own proper ideas, independently of the thoughts belonging to, and mixed up with, the senses; which thoughts are the causes of the mind's tendencies.... That these two diverse propensities of the will should be regarded as two distinct desires is occasioned by the fact that very often the one is opposed to the other, because the intention, which is built up by the mind on the foundation of its own proper perceptions, does not always agree with the thoughts which are suggested to the mind by the body's disposition; whereby it (the mind) is often constrained to will something, while its reason makes it choose something different.—(Translator.)
