No one in his senses would complain of the existence of animals inferior to man, if, besides, they contribute towards the embellishment of the universe. Would it not be ridiculous to complain that some of them bite men, as if the latter had an imprescriptible right to complete security? The existence of these animals is necessary; it procures us advantages both evident and still unknown, but which will be revealed in the course of time. Thus there is nothing useless in animals, either in respect to themselves, or to man.[54] It is, besides, ridiculous to complain because many animals are wild, when there are even men who are such; what should surprise us most is that many animals are not submissive to man, and defend themselves against him.[55] IF UNJUST ACTS ARE PRODUCED ASTROLOGICALLY THEN DIVINE REASON IS TO BLAME. 10. But if men be evil only in spite of themselves, and involuntarily, it would be impossible to say that those who commit injustices, and those who suffer them are responsible (the former for their ferocity, and the latter for their cowardice.[56] To this we answer that if the wickedness of the former (as well as the cowardice of the latter) be, necessarily, produced by the course of the stars, or by the action of a principle of which it is only the effect, then it is explained by physical reasons. But if it be the very Reason of the universe that produces such things, how does it not thereby commit an injustice? EVEN INVOLUNTARINESS DOES NOT AFFECT SPONTANEITY THAT IS RESPONSIBLE. Unjust actions are involuntary only in this sense that one does not have the will to commit a fault; but this circumstance does not hinder the spontaneity of the action. However, when one acts spontaneously, one is responsible for the fault; one would avoid responsibility for the fault only if one were not the author of the action. To say that the wicked are such necessarily, does not mean that they undergo an external constraint, but that their character is constituted by wickedness. The influence of the course of the stars does not destroy our liberty, for, if every action in us were determined by the exterior influence of such agents, everything would go on as these agents desired it; consequently, men would not commit any actions contrary to the will of these agents. If the divinities alone were the authors of all our actions, there would be no impious persons; therefore, impiety is due to men. It is true that, once the cause is given, the effects will follow, if only the whole series of causes be given. But man himself is one of these causes; he therefore does good by his own nature, and he is a free cause. EVEN THE SHADOWS ARE NECESSARY TO THE PERFECTION OF A PICTURE.
