In the mind there is no absolutely free will. The mind is determined to this or that volition by a cause, which is determined by another cause, and so on _ad infinitum_. The will and intellect are one and the same. We are partakers of the divine nature in proportion as we more and more understand God and conform our actions to his will. Our highest happiness consists in this conformity, by which alone the soul finds repose. Those greatly err from the true estimate of virtue who expect to be rewarded for it, as though virtue and the service of God were our felicity itself and the highest liberty. _III.--Concerning Mental Affections_ The actions of the mind arise from adequate ideas alone; but the passions depend on those alone which are inadequate. The essence of the mind is composed of adequate and inadequate ideas. Joy is a passion by which the mind passes to a greater degree of perfection; sorrow is a passion by which it passes to a lesser degree. Accidentally anything may be the cause of joy, sorrow, or desire. We love or hate certain things not from any known cause, but merely from sympathy or antipathy. If we hate a thing, we seek to affirm concerning it everything that we think can affect it with sorrow, while we deny everything that we think can affect it with joy. From this we see how easily a man may think too much of himself, and of the object which he loves, and on the other hand, may think too little of what he hates. When a man thinks too much of himself this imagination is termed pride, and is a species of delirium, because he dreams with his eyes open, that he can do all those things to which he attains in imagination alone, regarding them thus as realities, and rejoicing in them so long as he cannot imagine anything to exclude their existence and limit his power of action. If we imagine that a person loves, desires, or hates a thing which we love, desire, or hate, we shall on that account love, desire, or hate the thing more intensely. If, on the other hand, we imagine that he is averse to the thing we love, or loves the thing to which we are averse, then we shall suffer vacillation of mind. Hence every one strives to the utmost to induce others to love what he loves and to hate what he hates. This effort is called ambition, which prompts each person to desire that others should live according to his way of thinking. But if all thus act, then all hinder each other. And if all wish to be praised or loved by all, then all hate one another. Joy is a man's passage from a less to a greater perfection; sorrow is a man's passage from a greater to a less perfection. I say passage, for joy is not perfection itself. If a man were born with the perfection to which he passes, he would possess it without the affection of joy--a truth the more vividly apparent from the affection of sorrow which is the contrary of joy.
