A trader is a man who earns what he gets and does not give or take the undeserved.

An attempt to gain a value by deceiving the mind of others is an act of raising your victims to a position higher than reality.

There can be no causeless love or any sort of causeless emotion. An emotion is a response to a fact of reality, an estimate dictated by your standards.

A trader does not squander his body as fodder or his soul as alms.

As there can be no causeless wealth, so there can be no causeless love or any sort of causeless emotion.

If there are degrees of evil, it is hard to say who is more contemptible: the brute who assumes the right to force the mind of others or the moral degenerate who grants to others the right to force his mind.

Man cannot survive except by gaining knowledge, and reason is his only means to gain it.
