Now I assert that the mind and the soul are kept together in close union and make up a single nature, but that the directing principle which we call mind and understanding, is the head so to speak and reigns paramount in the whole body.
Truth is by its very nature intolerant, exclusive, for every truth is the denial of its opposing error.
Everything was possessed of personality, only different from us in form. Knowledge was inherent in all things. The world was a library and its books were the stones, leaves, grass, brooks, and the birds and animals that shared, alike with us, the storms and blessings of earth. We learned to do what only the student of nature ever learns, and that was to feel beauty... Observation was certain to have its rewards. Interest, wonder, admiration grew, and the fact was appreciated that life was more than mere human manifestation; it was expressed in a multitude of forms. This appreciation enriched Lakota existence. Life was vivid and pulsating; nothing was casual and commonplace. The Indian lived - lived in every sense of the word - from his first to his last breath.
You will be able to overcome desires without excessive difficulty when you become aware of their illusory nature. The pleasure of eating, for example, is really of very short duration. You feel the pleasure for only the short amount of time the food is in your mouth. As soon as you have swallowed the food, it is already forgotten... All physical pleasures are similar. Give the matter sufficient thought and you will realize that even the illusory good lasts only a short time. On the other hand, the negative consequences of physical pleasures can be severe and long lasting. A thinking person will definitely not want to place himself in a situation fraught with dangers for momentary pleasures. By habitually thinking about this truth, one will gradually be able to free himself from the prison of foolishly pursuing physical pleasures.
The virtue of benevolence... is of so comprehensive a nature, that it contains the principle of every moral duty.
Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio. A slight acquaintance with numbers will show the immensity of the first power in comparison to the second. By that law of our nature which makes food necessary to the life of man, the effects of these two unequal powers must be kept equal. This implies a strong and constantly operating check on population from the difficulty of subsistence. This difficulty must fall somewhere and must necessarily be severely felt by a large portion of mankind.
Since man is endowed with intelligence and determines his own ends, it is up to him to put himself in tune with the ends necessarily demanded by his nature. This means that there is, by very virtue of human nature, an order or a disposition which human reason can discover and according to which the human will must act in order to attune itself to the necessary ends of the human being. The unwritten law, or natural law, is nothing more than that.
Man's conquest of nature has been astonishing. His failure to conquer human nature has been tragic.
The man who strives to educate himself - and no one else can educate him - must win a certain victory over his own nature. He must learn to smile at his dear idols, analyze his every prejudice, scrap if necessary his fondest and most consoling belief, question his presuppositions, and take his chances with the truth.
Pride looks back upon its past deeds, and calculating with nicety what it has done, it commits itself to rest; whereas humility looks to that which is before, and discovering how much ground remains to be trodden, it is active and vigilant. Having gained one height, pride looks down with complacency on that which is beneath it; humility looks up to a higher and yet higher elevation. The one keeps us on this earth, which is congenial to its nature; the other directs our eye, and tends to lift us up to heaven.
The more one seeks ‘the good’ outside oneself as something to be acquired, the more one is faced with the necessity of discussing, studying, understanding, analysing the nature of good. the more, therfore, one becomes involved in abstractions and in the confusion of divergent opinions. The more ‘the good’ is objectively analysed, the more it is treated as something to be attained by special virtuous techniques, the less real it becomes.
The defects of human nature afford us opportunities of exercising our philosophy, the best employment of our virtues. If all men were righteous, all hearts true and frank and loyal, what use would our virtues be?
Human beings are not born with human nature - they develop it.
Many persons, after they become learned cease to be good; all other knowledge is hurtful to him who has not the science of honesty and good nature.
The laws of conscience, which we say are born of nature, are born of custom. Each man, holding in inward veneration the opinions and the behavior approved and accepted around him, cannot break loose from them without remorse, or apply himself to them without self-satisfaction.
The truth is that it is contrary to the nature of love if it is not violent, and contrary to the nature of violence if it is constant.
Through a fatality inseparable from human nature, moderation in great men is very rare: and as it is always much easier to push on force in the direction in which it moves than to stop its movement, so in the superior class of the people, it is less difficult, perhaps, to find men extremely virtuous, than extremely prudent.
You have not converted a man, because you have silenced him... The small reform may become the enemy of the great one... The most frightful idea that has ever corroded human nature-the idea of eternal punishment.
All of our capacities, whether normal or metamornal, somatic or extrasomatic, are subject to the limitations and distortions produced by our inhereited and socially conditioned nature.
Exceptional abilities develop most fully in cultures that prize them... no aspect of human nature is immune to social influence.
