A Quote by Robert A. Heinlein

The greatest productive force is human selfishness. — © Robert A. Heinlein
The greatest productive force is human selfishness.
Selfishness is the greatest curse of the human race.
I heard of somebody once who said he was interested in doing the greatest amount of good for the greatest number, and that the greatest number was number one. That was himself. That may sound like a little bit of selfishness, but if that is selfishness, at least it is a very intelligent selfishness. Everyone has a right to be interested in himself, and I am confident that God wants us to be interested in ourselves first; that is, the first soul that anyone should bring to God should be his own soul.
The greatest surprise of human evolution may be that the highest form of selfishness is selflessness.
In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction.
The force of selfishness is as inevitable and as calculable as the force of gravitation.
The greatest force in the human body is the natural drive of the body to heal itself - but that force in not independent of the belief system. Everything begins with belief. What we believe is the most powerful option of all.
Government began in tyranny and force, began in the feudalism of the soldier and bigotry of the priest; and the ideas of justice and humanity have been fighting their way, like a thunderstorm, against the organized selfishness of human nature.
Selfishness is one of the principal fruits of the corruption of human nature; and it is obvious that selfishness disposes us to over-rate our good qualities, and to overlook or extenuate our defects.
The study of letters is the study of the operation of human force, of human freedom and activity; the study of nature is the study of the operation of non-human forces, of human limitation and passivity. The contemplation of human force and activity tends naturally to heighten our own force and activity; the contemplation of human limits and passivity tends rather to check it. Therefore the men who have had the humanistic training have played, and yet play, so prominent a part in human affairs, in spite of their prodigious ignorance of the universe.
Evil itself may be relentless. I will grant you that, but love is relentless too. Friendship is a relentless force. Family is a relentless force. Faith is relentless force. The human spirit is relentless, and the human heart outlasts - and can defeat - even the most relentless force of all, which is time.
In one degree or another we all struggle with selfishness. Since it is so common, why worry about selfishness anyway? Because selfishness is really self-destruction in slow motion.
The ruling of men is the effort to direct the individual actions of many persons toward some end. This end theoretically should be the greatest good of all, but no human group has ever reached this ideal because of ignorance and selfishness.
Satan had two conditions [to his plan]: the first was the denial of agency, and the second, that he would have the honor. In other words, something had to be in it for him. And thus he became the father of lies and selfishness. Taking up one's cross and following the Savior means overcoming selfishness; it is a commitment to serve others. Selfishness is one of the baser human traits, which must be subdued and overcome. We torture our souls when we focus on getting rather than giving.
Intellectual force is qualitatively the first and foremost productive force, and concern for its rapid growth should be the ardent concern of all classes.
Why fight the 'natural' (oh, weaselly word!) order of things? Why? Because of this--one fine day, a purely predatory world shall consume itself. In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction.
There is only one force stronger than selfishness, and that is stupidity.
