Perfecting one's intellect causes one to speak less, and those words spoken will be adorned with wisdom.

When proven wrong, the wise man will correct himself and the ignorant will keep arguing.

The world is darkness; knowledge is light; but knowledge without truth is a mere shadow.

Perfecting one's intellect causes one to speak less, and those words spoken will be adorned with wisdom.

Be afraid of a dignified man when he is hungry and a wicked man when his belly is full.

The highest person is he who is of most use to humankind.

A wise man first thinks and then speaks and a fool speaks first and then thinks.
