“The only justifiable stopping place for for the expansion of altruism is the point at which all whose welfare can be affected by our actions are included within the circle of altruism. This means that all beings with the capacity to feel pleasure or pain should be included; we can improve their welfare by increasing their pleasures and diminishing their pains.”

“By feeling the sunshine, or pleasure, we end up forgetting all of our miseries, or pains in life.”

“By a commodity we shall understand any object, substance, action or service, which can afford pleasure or ward off pain.”

“For how can you remember the feel of pleasure or pain or choking emotion? You can remember only that you had them.”

“Why do we have such a finite capacity for pleasure but an infinite one for pain?”

“Pleasure is never as pleasant as we expected it to be and pain is always more painful. The pain in the world always outweighs the pleasure. If you don't believe it, compare the respective feelings of two animals, one of which is eating the other.”

“We make no hypocritical pretense of being interested in the Philippines solely on account of others. While we regard the welfare of these people as a sacred trust, we regard the welfare of the American people first. We see our duty to ourselves as well as to others. We believe in trade expansion. By every legitimate means within the province of government and constitution we mean to stimulate the expansion of our trade and open new markets.”

“Pleasure can only be experienced after going through pain and vice versa.”

“Longitudinal or serial altruism, that is, altruism toward the generations in future time, arises, like lateral or space altruism, thru sympathy, that is, thru the imagination. The living sustain a vital relation to the unborn. Every one who recognizes and shows any regard for this relation, and there are very few who do, does so by putting himself in the place of the unborn billions, and by anticipation sharing their welfare and ill-fare.”

“Emotions are continually affecting our thought processes and decisions, below the level of our awareness. And the most common emotion of them all is the desire for pleasure and the avoidance of pain. Our thoughts almost inevitably revolve around this desire; we simply recoil from entertaining ideas that are unpleasant or painful to us. We imagine we are looking for the truth, or being realistic, when in fact we are holding on to ideas that bring a release from tension and soothe our egos, make us feel superior. This pleasure principle in thinking is the source of all of our mental biases. If you believe that you are somehow immune to any of the following biases, it is simply an example of the pleasure principle in action. Instead, it is best to search and see how they continually operate inside you, as well as learn how to identify such irrationality in others.”
