“There are only a few natural forces in this world that can make a rational man go against his judgment: love and greed.”

“There is a collision course between the greed and rationalizations of the West and the force of nature; science and the planet are the casualties.”

“Of all the forces, love is the strongest...Love can make a woman pick up a bus, or it can crush a man under the weight of a feather. Or it just lets everything go on as it was yesterday and will be tomorrow. That’s the kind of force love is.”

“A rational man never distorts or corrupts his own standards and judgment in order to appeal to the irrationality, stupidity, or dishonesty of others.”

“The source of man's rights is not divine law or a congressional law, but the law of identity. A is A ___ and man is man. Rights are conditions of existence required by man's nature for his proper survival. If man is to live on earth, it is right for him to use his mind, it is right to act on his own free judgment, it is right to work for his values and to keep the product for his work. If life on earth is his purpose, he has a right to live as a rational being: nature forbids him the irrational”

“For the Stoics, then, our judgments about the world are all that we can control, but also all that we need to control in order to be happy; tranquility results from replacing our irrational judgments with rational ones”
