“But today’s society is characterized by achievement orientation, and consequently it adores people who are successful and happy and, in particular, it adores the young. It virtually ignores the value of all those who are otherwise, and in so doing blurs the decisive difference between being valuable in the sense of dignity and being valuable in the sense of usefulness. If one is not cognizant of this difference and holds that an individual’s value stems only from his present usefulness, then, believe me, one owes it only to personal inconsistency not to plead for euthanasia along the lines of Hitler’s program, that is to say, ‘mercy’ killing of all those who have lost their social usefulness, be it because of old age, incurable illness, mental deterioration, or whatever handicap they may suffer. Confounding the dignity of man with mere usefulness arises from conceptual confusion that in turn may be traced back to the contemporary nihilism transmitted on many an academic campus and many an analytical couch.”

“We stand at the crossroads, each minute, each hour, each day, making choices. We choose the thoughts we allow ourselves to think, the passions we allow ourselves to feel, and the actions we allow ourselves to perform. Each choice is made in the context of whatever value system we have selected to govern our lives. In selecting that value system, we are, in a very real way, making the most important choice we will ever make.Those who believe there is one God who made all things and who governs the world by this providence will make many choices different from those who do not. Those who hold in reverence that being who gave them life and worship Him through adoration, prayer, and thanksgiving will make choices different from those who do not. Those who believe that mankind are all of a family and that the most acceptable service of God is doing good to man will make many choices different from those who do not. Those who believe in a future state in which all that is wrong here will be made right will make many choices different from those who do not. Those who subscribe to the morals of Jesus will make many choices different from those who do not.Since the foundation of all happiness is thinking rightly, and since correct action is dependent on correct opinion, we cannot be too careful in choosing the value system we allow to govern our thoughts and actions.And to know that God governs in the affairs of men, that He hears and answers prayers, and that He is a rewarder of them that diligently seek Him, is, indeed, a powerful regulator of human conduct.”

“The necessary consequence of man's right to life is his right to self-defense. In a civilized society, force may be used only in retaliation and only against those who initiate its use. All the reasons which make the initiation of physical force an evil, make the retaliatory use of physical force a moral imperative.If some "pacifist" society renounced the retaliatory use of force, it would be left helplessly at the mercy of the first thug who decided to be immoral. Such a society would achieve the opposite of its intention: instead of abolishing evil, it would encourage and reward it.”

“All I have learned in life really just boils down to this: there is only one difference between the so-called wise and the so-called foolish...and between those who are truly happy and those who are not. Those who are wise - and those who are happy - embrace and appreciate life. Those who are unhappy and unwise do not. That is all; that is the only difference.”

“On the average, only those prisoners could keep alive who, after years of trekking from camp to camp, had lost all scruples in their fight for existence; they were prepared to use every means, honest and otherwise, even brutal force, theft, and betrayal of their friends, in order to save themselves. We who have come back, by the aid of many lucky chances or miracles - whatever one may choose to call them - we know: the best of us did not return.”

“I used to feel so alone in the city. All those gazillions of people and then me, on the outside. Because how do you meet a new person? I was very stunned by this for many years. And then I realized, you just say, "Hi." They may ignore you. Or you may marry them. And that possibility is worth that one word.”
