The principal of ethics being a categorical imperative does not admit of proof, but it admits of a justification from principles of pure practical reason.

There are too many who reserve both the principles and the practice of the Apostles; they become all things to all men, not to serve others, but themselves; and they try all things only to hold fast that which is bad.

All reason is retrospect; it consists in the application of facts and principles previously known. This will show the very great importance of knowledge, especially that kind which is called experience.

The perspective of eternity is not a perspective from a certain place beyond the world, nor the point of view of a transcendent being; rather it is a certain form of thought and feeling that rational persons can adopt within the world. And having done so, they can, whatever their generation, bring together into one scheme all individual perspectives and arrive together at regulative principles that can be affirmed by everyone as he lives by them, each from his own standpoint. Purity of heart, if one could attain it, would be to see clearly and to act with grace and self-command from this point of view.

The macrocosm (order of the universe), microcosm (order of the individual), and mesocosm (order of the attuned society) are equivalent, the social ideas and moral principles by which the individual is constrained to his group are conceived to be, finally, of his own nature. And for the same reason, the visionary realizations of the yogi in solitude would be of the psychological sources out of which the mesocosmic order of his mythologically grounded cultural monad originated.

Those of us who shout the loudest about Americanism in making character assassinations are all too frequently those who, by our own words and acts, ignore some of the basic principles of Americanism - The right to criticize. The right to hold unpopular beliefs. The right to protest. The right of independent thought. The exercise of these rights should not cost one single American citizen his reputation or his right to a livelihood nor should he be in danger of losing his reputation or livelihood merely because he happens to know someone who holds unpopular beliefs. Who of us does not? Otherwise none of us could call our souls our own. Otherwise thought control would have set in. The American people are sick and tired of being afraid to speak their minds lest they be politically smeared as Communists or Fascists by their opponents. Freedom of speech is not what is used to be in America. It has been so abused by some that it is not exercised by others. The American people are sick and tired of seeing innocent people smeared and guilty people whitewashed.

Ethics is putting principles into action. Consistently between what we say we value and what our actions say we value is a matter of integrity.

Our capacity to reason and our freedom to choose make us morally autonomous and, therefore, answerable for whether we honor or degrade the ethical principles that give life meaning and purpose.

Though the ethical challenges we face in the workplace may be different from those in our personal lives, the principles of ethical conduct that apply to those challenges do not change. There is no such thing as business ethics - there is only ethics.

We really don't know what the fundamental principles of moral judgment actually are, but we have very good reason to believe that they're there.

In my experience, very few politicians have solid principles that they are unwilling to sell out for the sake of winning elections. They are, most of them, "the hollow men, stuffed men" of whom T. S. Eliot wrote, and in Clinton we have perhaps as extreme an embodiment of this professional deformation as can be unearthed.

To practice the basic principles of good health, visualize yourself as sound, healthy and filled with vitality and boundless life of your Creator. Look upon yourself as the unique individual that you are. Get in harmony with the creative, life-giving, health-maintaining forces of the universe. Affirm peace, wholeness, and good health - and they will be yours.

To have doubted one's own first principles is the mark of a civilized man.

All calm inquiry conducted among those who have their main principles of judgment in common, leads, if not to an approximation of views, yet, at least, to an increase of sympathy.

General principles are not the less true or important because from their nature they elude immediate observation; they are like the air, which is not the less necessary because we neither see nor feel it.

The principles of war, not merely one principle, can be condensed into a single word - "Concentration." But the truth this needs to be amplified as the concentration of strength against weakness. And for real value, it needs to be explained that the concentration of strength against weakness depends on the dispersion of your opponent's strength.

The Ethics and equity and the principles of justice do not change with the calendar.

Every principle is a judgment, every judgment the outcome of experience, and experience is only acquired by the exercise of the senses; whence it follows that religious principles bear upon nothing whatever and are not in the slightest innate.

Nothing, in truth, has such a tendency to weaken not only the powers of invention, but the intellectual powers in general, as a habit of extensive and various reading without reflection. The activity and force of mind are gradually impaired in consequence of disuse; and, not infrequently, all our principles and opinions come to be lost in the infinite multiplicity and discordancy of our acquired ideas.

True character arises from a deeper well than religion. It is the internalization of moral principles of a society, augmented by those tenets personally chosen by the individual, strong enough to endure through trials of solitude and adversity. The principles are fitted together into what we call integrity, literally the integrated self, wherein personal decisions feel good and true. Character is in turn the enduring source of virtue. It stands by itself and excites admiration in others.
