Whoever acquires knowledge and does not practise it resembles him who ploughs his land and leaves it unsown.

XLVI
It is not every man that has a handsome physical exterior that has a good moral character; for the faculty of business or virtue resides in the heart and not in the skin. Thou canst in one day ascertain the intellectual faculties of a man, and what proficiency he has made in his degrees of knowledge; but be not secure of his mind, nor foolishly sure, for it may take years to detect the innate baseness of the heart.
XLVII
Whoever contends with the great sheds his own blood:—Thou contemplatest thyself as a mighty great man; and they have truly remarked that the squinter sees double. Thou who canst in play butt with a ram must soon find thyself with a broken pate.
XLVIII
To grapple with a lion, or to box against a naked scimitar, are not the acts of the prudent:—Brave not the furious with war and opposition before their arms of strength cross thy hands of submission.
