288. I have proved that free will is the proximate cause of the evil of guilt, and consequently of the evil of punishment; although it is true that the original imperfection of creatures, which is already presented in the eternal ideas, is the first and most remote cause. M. Bayle [303] nevertheless always disputes this use of the notion of free will; he will not have the cause of evil ascribed to it. One must listen to his objections, but first it will be well to throw further light on the nature of freedom. I have shown that freedom, according to the definition required in the schools of theology, consists in intelligence, which involves a clear knowledge of the object of deliberation, in spontaneity, whereby we determine, and in contingency, that is, in the exclusion of logical or metaphysical necessity. Intelligence is, as it were, the soul of freedom, and the rest is as its body and foundation. The free substance is self-determining and that according to the motive of good perceived by the understanding, which inclines it without compelling it: and all the conditions of freedom are comprised in these few words. It is nevertheless well to point out that the imperfection present in our knowledge and our spontaneity, and the infallible determination that is involved in our contingency, destroy neither freedom nor contingency. 289. Our knowledge is of two kinds, distinct or confused. Distinct knowledge, or _intelligence_, occurs in the actual use of reason; but the senses supply us with confused thoughts. And we may say that we are immune from bondage in so far as we act with a distinct knowledge, but that we are the slaves of passion in so far as our perceptions are confused. In this sense we have not all the freedom of spirit that were to be desired, and we may say with St. Augustine that being subject to sin we have the freedom of a slave. Yet a slave, slave as he is, nevertheless has freedom to choose according to the state wherein he is, although more often than not he is under the stern necessity of choosing between two evils, because a superior force prevents him from attaining the goods whereto he aspires. That which in a slave is effected by bonds and constraint in us is effected by passions, whose violence is sweet, but none the less pernicious. In truth we will only that which pleases us: but unhappily what pleases us now is often a real evil, which would displease us if we had the eyes of the understanding open. Nevertheless that evil state of the slave, which is also our own, does not prevent us, any more than him, from making a free choice of that which pleases us most, in the state to which we are reduced, in proportion to our present strength and knowledge.
