Once you teach people to say what they do not understand, it is easy enough to get them to say anything you like.

The abuse of books kills science. Believing that we know what we have read, we believe that we can dispense with learning it.

War is then not a relationship between one man and another, but a relationship between one State and another, in which individuals are enemies only by accident, not as men, nor even as citizens, but as soldiers; not as members of the fatherland, but as its defenders.
