How would it be possible if salvation were ready to our hand, and could without great labor be found, that it should be by almost all men neglected? But all things excellent are as difficult as they are rare.

True virtue is life under the direction of reason.

...The body is affected by the image of the thing, in the same way as if the thing were actually present.

Be not astonished at new ideas; for it is well known to you that a thing does not therefore cease to be true because it is not accepted by many.

The things which ... are esteemed as the greatest good of all ... can be reduced to these three headings, to wit : Riches, Fame, and Pleasure. With these three the mind is so engrossed that it cannot scarcely think of any other good.

In regard to intellect and true virtue, every nation is on a par with the rest, and God has not in these respects chosen one people rather than another.

Nature is satisfied with little; and if she is, I am also.
