“A severe morality holds that intercourse (and may hold this of eating, too) has something wrong about it if it is ever done except explicitly as being required for that preservation of human life which is what makes intercourse a good kind of action. But this involves thoroughly faulty moral psychology. God gave us our physical appetite, and its arousal without our calculation is part of the working of our sort of life. Given moderation and right circumstances, acts prompted by inclination can be taken in a general way to accomplish what makes them good in kind and there's no need for them to be individually necessary or useful for the end that makes them good kinds of action. Intercourse is a normal part of married life through the whole life of the partners in a marriage and is normally engaged in without any distinct purpose other than to have it, just as such a part of married life.”

Letter to the minister of a church in Brooklyn (20 November 1950), p. 95. The minister had earlier written Einstein asking if he would send him a signed version of a quote about the Catholic church attributed to Einstein in Time magazine (see the "Misattributed" section below), and Einstein had written back to say the quote was not correct, but that he was "gladly willing to write something else which would suit your purpose". According to the book, the minister replied "saying he was glad the statement had not been correct since he too had reservations about the historical role of the Church at large", and said that "he would leave the decision to Einstein as to the topic of the statement", to which Einstein replied with the statement above.

Context: The most important human endeavor is the striving for morality in our actions. Our inner balance and even our very existence depend on it. Only morality in our actions can give beauty and dignity to life. To make this a living force and bring it to clear consciousness is perhaps the foremost task of education. The foundation of morality should not be made dependent on myth nor tied to any authority lest doubt about the myth or about the legitimacy of the authority imperil the foundation of sound judgment and action.

Context: While birds can fly, only humans can argue. Argument is the affirmation of our being. It is the principal instrument of human intercourse. Without argument the species would perish. As a subtle suggestion, it is the means by which we aid another. As a warning, it steers us from danger. As exposition, it teaches. As an expression of creativity, it is the gift of ourselves. As a protest, it struggles for justice. As a reasoned dialogue, it resolves disputes. As an assertion of self, it engenders respect. As an entreaty of love, it expresses our devotion. As a plea, it generates mercy. As charismatic oration it moves multitudes and changes history. We must argue — to help, to warn, to lead, to love, to create, to learn, to enjoy justice — to be.
