Knowledge

All men by nature desire to know. An indication of this is the delight we take in our senses; for even apart from their usefulness they are loved for themselves; and above all others the sense of sight. For not only with a view to action, but even when we are not going to do anything, we prefer seeing (one might say) to everything else. The reason is that this, most of all the senses, makes us know and brings to light many differences between things.

Homer saw that the story would not be probable if he represented so great a man as caught by mere songs; so they promise him knowledge, which it was not strange that a man desirous of wisdom should consider dearer than his country. And, indeed, to wish to know everything of every kind, is natural to the curious; but, to be attracted by the contemplation of greater objects, to entertain a general desire for knowledge, ought to be considered a proof of a great man.

For there resides in every man a natural desire to know the cause of any effect which he sees; and thence arises wonder in men. But if the intellect of the rational creature could not reach so far as to the first cause of things, the natural desire would remain void.
