301. The spontaneity of our actions can therefore no longer be questioned; and Aristotle has defined it well, saying that an action is [310] _spontaneous_ when its source is in him who acts. 'Spontaneum est, cujus principium est in agente.' Thus it is that our actions and our wills depend entirely upon us. It is true that we are not directly the masters of our will, although we be its cause; for we do not choose volitions, as we choose our actions by our volitions. Yet we have a certain power also over our will, because we can contribute indirectly towards willing another time that which we would fain will now, as I have here already shown: that, however, is no _velleity_, properly speaking. There also we have a mastery, individual and even perceptible, over our actions and our wills, resulting from a combination of spontaneity with intelligence. 302. Up to this point I have expounded the two conditions of freedom mentioned by Aristotle, that is, _spontaneity_ and _intelligence_, which are found united in us in deliberation, whereas beasts lack the second condition. But the Schoolmen demand yet a third, which they call _indifference_. And indeed one must admit it, if indifference signifies as much as 'contingency'; for I have already said here that freedom must exclude an absolute and metaphysical or logical necessity. But, as I have declared more than once, this indifference, this contingency, this non-necessity, if I may venture so to speak, which is a characteristic attribute of freedom, does not prevent one from having stronger inclinations towards the course one chooses; nor does it by any means require that one be absolutely and equally indifferent towards the two opposing courses. 303. I therefore admit indifference only in the one sense, implying the same as contingency, or non-necessity. But, as I have declared more than once, I do not admit an indifference of equipoise, and I do not think that one ever chooses when one is absolutely indifferent. Such a choice would be, as it were, mere chance, without determining reason, whether apparent or hidden. But such a chance, such an absolute and actual fortuity, is a chimera which never occurs in nature. All wise men are agreed that chance is only an apparent thing, like fortune: only ignorance of causes gives rise to it. But if there were such a vague indifference, or rather if we were to choose without having anything to prompt us to the choice, chance would then be something actual, resembling what, according to Epicurus, took place in that little deviation of the atoms, occurring without cause or reason. Epicurus had introduced it in order to evade necessity, and[311] Cicero with good reason ridiculed it.
