Choosing effective guides to action is not a matter for blind faith or reasonless whim; it requires clear, rational thought. Therefore, one's morality shouldn't be a set of dos and don'ts inherited from one's parents or learned in church or school. It should be a clearly thought-out code, guiding one toward pro-life actions and away from anti-life actions. "The purpose of morality is . . . to teach you to enjoy yourself and live." A rational morality doesn't say, "Don't do this because God (or society, or legal authorities, or tradition) says it's evil." It does say, "Only if you act according to your reason can you have a happy, satisfying life."
In any code of morality, there must be a standard—a standard by which all goals and actions can be judged. Only life makes values meaningful . . . or even possible—if you're dead you can't experience any values at all (and without values, happiness is impossible). So, for each man who values living, his own life is his
moral standard (death, the negation of all values, is the only alternative "standard"). Since each man's own life is his objective standard, it follows that whatever serves or enhances his life and well-being is good, and whatever damages or destroys it is wrong. In a rational morality—one designed to further each individual man's life and happiness, whatever is pro-life is moral and whatever is anti-life is immoral. By "life" is not meant merely man's physical existence but all aspects of his life as a sensing, thinking being. Only by rational thought and action can a man's life be lived to its fullest potential, producing the greatest possible happiness and satisfaction for him.
Man has only one tool for getting knowledge—his mind, and only one means to know what is beneficial and harmful—his faculty of reason. Only by thinking can he know what will further his life and what will harm it. For this reason, choosing to think is man's most powerful tool and greatest virtue, and refusing to think is his greatest danger, the surest way to bring him to destruction.
Since man's life is what makes all his values possible, morality means acting in his own self-interest, which is acting in a pro-life manner. There is nothing mystical or hard to understand about right and wrong—a rational morality makes sense. Traditional morality, teaching that each man must devote a part of his life, not primarily for his own good, but for God or the State or "the common good," regards man as a sacrificial animal. Today, many are recognizing this doctrine for what it is—the cause of incalculable human carnage, and a morality or life is gradually replacing it. A rational morality is a morality of self-interest—a pro-life morality.
The only way for a man to know what will further his life is by a process of reason; morality, therefore, means acting in his rational self-interest (in fact, no other kind of self-interest exists, since only that which is rational is in one's self-interest). Sacrifice (the act of giving up a greater value for a lesser value, a non-value, or a dis-value) is always wrong, because it is destructive of the life and well-being of the sacrificing individual. In spite of traditional "moralities" which glorify "a life of sacrificial service to others," sacrifice can never benefit anyone. It demoralizes both the giver, who has diminished his total store of value, and the recipient, who feels guilty about accepting the sacrifice and resentful because he feels he is morally bound to return the "favor" by sacrificing some value of his own. Sacrifice, carried to its ultimate end, results in death; it is the exact opposite of moral, pro-life behavior, traditional "moralists" to the contrary notwithstanding.
A man who is acting in his own self-interest (that is, who is acting morally) neither makes sacrifices nor demands that others sacrifice for him. There is no conflict of interest between men who are each acting in his own self-interest, because it is not in the interest of either to sacrifice for the other or to demand a sacrifice from the other. Conflicts are produced when men ignore their self-interest and accept the notion that sacrifice is beneficial; sacrifice is always anti-life.
In summary: man, by his nature, must choose to think and produce in order to live, and the better he thinks, the better he will live. Since each man's own life makes his values possible, chosen behavior which furthers his life as a thinking being is the moral, and chosen behavior which harms it is the immoral. (Without free choice, morality is impossible.) Therefore, rational thought and action and their rewards, emotional, physical, and material, are the whole of a man's self-interest. The opposite of self-interest is sacrifice which is always wrong because it's destructive of human life.
