The Pragmatics of Patriotism (1973)
Context: Selfishness is the bedrock on which all moral behavior starts and it can be immoral only when it conflicts with a higher moral imperative. An animal so poor in spirit that he won't even fight on his own behalf is already an evolutionary dead end; the best he can do for his breed is to crawl off and die, and not pass on his defective genes.

Context: Now this conjunction of an immense military establishment and a large arms industry is new in the American experience. The total influence — economic, political, even spiritual — is felt in every city, every Statehouse, every office of the Federal government. We recognize the imperative need for this development. Yet we must not fail to comprehend its grave implications. Our toil, resources, and livelihood are all involved. So is the very structure of our society.
In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex. The potential for the disastrous rise of misplaced power exists and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together.

The Passionate State Of Mind, and Other Aphorisms (1955)
Context: Pride is a sense of worth derived from something that is not organically part of us, while self-esteem derives from the potentialities and achievements of the self. We are proud when we identify ourselves with an imaginary self, a leader, a holy cause, a collective body or possessions. There is fear and intolerance in pride; it is sensitive and uncompromising. The less promise and potency in the self, the more imperative is the need for pride. The core of pride is self-rejection.
It is true that when pride releases energies and serves as a spur to achievement, it can lead to a reconciliation with the self and the attainment of genuine self-esteem.
