“There are certain prejudices attached to the human mind which it requires all our wisdom to keep from interfering with our happiness; certain set notions, acquired in infancy, and cherished involuntarily by age, which grow up and assume a gloss so plausible, that few minds, in what is called a civilized country, can afterwards overcome them. Truth is often perverted by education. While the refined Europeans boast a standard of honour, and a sublimity of virtue, which often leads them from pleasure to misery, and from nature to error, the simple, uninformed American follows the impulse of his heart, and obeys the inspiration of wisdom.Nature, uncontaminated by false refinement, every where acts alike in the great occurrences of life. The Indian discovers his friend to be perfidious, and he kills him; the wild Asiatic does the same; the Turk, when ambition fires, or revenge provokes, gratifies his passion at the expence of life, and does not call it murder. Even the polished Italian, distracted by jealousy, or tempted by a strong circumstance of advantage, draws his stiletto, and accomplishes his purpose. It is the first proof of a superior mind to liberate itself from the prejudices of country, or of education… Self-preservation is the great law of nature; when a reptile hurts us, or an animal of prey threatens us, we think no farther, but endeavour to annihilate it. When my life, or what may be essential to my life, requires the sacrifice of another, or even if some passion, wholly unconquerable, requires it, I should be a madman to hesitate.”

“Let us not, in the pride of our superior knowledge, turn with contempt from the follies of our predecessors. The study of the errors into which great minds have fallen in the pursuit of truth can never be uninstructive. As the man looks back to the days of his childhood and his youth, and recalls to his mind the strange notions and false opinions that swayed his actions at the time, that he may wonder at them; so should society, for its edification, look back to the opinions which governed ages that fled.”

“Satan frequently steals the will of God from us due to reasoning. The Lord may direct us to do a certain thing, but if it does not make sense - if it is not logical - we may be tempted to disregard it. What God leads a person to do does not always make logical sense to his mind. His spirit may affirm it and His mind reject it, especially if it would be out of the ordinary or unpleasant or if it would require personal sacrifice or discomfort.”

“One realizes that even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbour’s household, and, underneath, another – secret and passionate and intense – which is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him. One realizes that human relationships are the tragic necessity of human life; that they can never be wholly satisfactory, that every ego is half the time greedily seeking them, and half the time pulling away from them. In those simple relationships of loving husband and wife, affectionate sisters, children and grandmother, there are innumerable shades of sweetness and anguish which make up the pattern of our lives day by day . . .”

“Trust a witness in all matters in which neither his self-interest, his passions, his prejudices, nor the love of the marvellous is strongly concerned. When they are involved, require corroborative evidence in exact proportion to the contravention of probability by the thing testified.”

“Humans are often credited with having real foresight, in distinction to the rest of biology which does not. For example, Dawkins compares the 'blind watchmaker' of natural selection with the real human one. 'A true watchmaker has foresight: he designs his cogs and springs, and plans their interconnections, with a future purpose in his mind's eye. Natural selection . . . has no purpose in mind'.I think this distinction is wrong. There is no denying that the human watchmaker is different from the natural one. We humans, by virtue of having memes, can think about cogs, and wheels, and keeping time, in a way that animals cannot. Memes are the mind tools with which we do it. But what memetics shows us is that the processes underlying the two kinds of design are essentially the same. They are both evolutionary processes that give rise to design through selection, and in the process they produce what looks like foresight.”
