The unconscious or minute ideas, which in noetics had served to break the force of Locke’s objections against the innateness of the principles of reason, are in ethics brought into the field against indeterminism. They are involved whenever we believe ourselves to act without cause, from pure choice, or contrary to the motives present. In this last case, a motive which is very strong in itself is overcome by the united power of many in themselves weaken The will is always determined, and that by an idea (of ends), which generally is of a very complex nature, and in which the stronger side decides the issue. An absolute equilibrium of motives is impossible: the world cannot be divided into two entirely similar parts (this in opposition to “Buridan’s ass"). A spirit capable of looking us through and through would be able to calculate all our volitions and actions beforehand.
In spite of this admitted inevitableness of our resolutions and actions, the predicate of freedom really belongs to them, and this on two grounds. First, they are only physically or morally, not metaphysically, necessary; as a matter of fact, it is true, they cannot happen otherwise, but their opposite involves no logical contradiction and remains conceivable. To express this thought the formula, often repeated since, that our motives only impel, incite, or stimulate the will, but do not compel it (inclinant, non necessitant), was chosen, but not very happily. Secondly, the determination of the will is an inner necessitation,
