It is the habit of many to dispute (antilegein) about everything in the same way,

but they do not yet have the habit of disputing correctly (orthōs).

Against these men one old saying is sufficient:

“let that be your opinion; let this be mine.”

But one would most quickly persuade intelligent men by speaking well,

for these men are easy to teach.

I think it not the least part of wisdom

to know correctly what each man is like.

To have boldness together with wisdom is a great advantage,

but by itself it is harmful and brings evil.

I say that training, my friend, lasts a long time; and in the end, this is nature (phusis) for men.
