Moreover, wherever an opportunity was afforded, I have endeavored to remove prejudices which might hinder the perception of the truth of what I have demonstrated; but because not a few still remain which have been and are now sufficient to prove a very great hindrance to the comprehension of the connection of things in the manner in which I have explained it, I have thought it worth while to call them up to be examined by reason. But all these prejudices which I here undertake to point out depend upon this solely: that it is commonly supposed that all things in Nature, like men, work to some end; and indeed it is thought to be certain that God Himself directs all things to some sure end, for it is said that God has made all things for man, and man that he may worship God. This, therefore, I will first investigate by inquiring, firstly, why so many rest in this prejudice, and why all are so naturally inclined to embrace it? I shall then show its falsity, and, finally, the manner in which there have arisen from it prejudices concerning _good_ and _evil_, _merit_ and _sin_, _praise_ and _blame_, _order_ and _disorder_, _beauty_ and _deformity_, and so forth. This, however, is not the place to deduce these things from the nature of the human mind. It will be sufficient if I here take as an axiom that which no one ought to dispute, namely, that man is born ignorant of the causes of things, and that he has a desire, of which he is conscious, to seek that which is profitable to him. From this it follows, firstly, that he thinks himself free because he is conscious of his wishes and appetites, whilst at the same time he is ignorant of the causes by which he is led to wish and desire, not dreaming what they are; and, secondly, it follows that man does everything for an end, namely, for that which is profitable to him, which is what he seeks. Hence it happens that he attempts to discover merely the final causes of that which has happened; and when he has heard them he is satisfied, because there is no longer any cause for further uncertainty. But if he cannot hear from another what these final causes are, nothing remains but to turn to himself and reflect upon the ends which usually determine him to the like actions, and thus by his own mind he necessarily judges that of another.
