“The dilemma is this. In the modern world knowledge has been growing so fast and so enormously, in almost every field, that the probabilities are immensely against anybody, no matter how innately clever, being able to make a contribution in any one field unless he devotes all his time to it for years. If he tries to be the Rounded Universal Man, like Leonardo da Vinci, or to take all knowledge for his province, like Francis Bacon, he is most likely to become a mere dilettante and dabbler. But if he becomes too specialized, he is apt to become narrow and lopsided, ignorant on every subject but his own, and perhaps dull and sterile even on that because he lacks perspective and vision and has missed the cross-fertilization of ideas that can come from knowing something of other subjects.”

“There is a strange idea abroad, held by all monetary cranks, that credit is something a banker gives to a man. Credit, on the contrary, is something a man already has. He has it, perhaps, because he already has marketable assets of a greater cash value than the loan for which he is asking. Or he has it because his character and past record have earned it. He brings it into the bank with him. That is why the banker makes him the loan. The banker is not giving something for nothing.”

“A man with a scant vocabulary will almost certainly be a weak thinker. The richer and more copious one's vocabulary and the greater one's awareness of fine distinctions and subtle nuances of meaning, the more fertile and precise is likely to be one's thinking. Knowledge of things and knowledge of the words for them grow together. If you do not know the words, you can hardly know the thing.”

“A man should begin with his own times. He should become acquainted first of all with the world in which he is living and participating. He should not be afraid of reading too much or too little. He should take his reading as he does his food or his exercise. The good reader will gravitate to the good books. He will discover from his contemporaries what is inspiring or fecundating, or merely enjoyable, in past literature. He should have the pleasure of making these discoveries on his own, in his own way. What has worth, charm, beauty, wisdom, cannot be lost or forgotten. But things can lose all value, all charm and appeal, if one is dragged to them by the scalp.”

“The whole gospel of Karl Marx can be summed up in a single sentence: Hate the man who is better off than you are. Never under any circumstances admit that his success may be due to his own efforts, to the productive contribution he has made to the whole community. Always attribute his success to the exploitation, the cheating, the more or less open robbery of others. Never under any circumstances admit that your own failure may be owing to your own weakness, or that the failure of anyone else may be due to his own defects - his laziness, incompetence, improvidence, or stupidity.”

“A house without books is like a room without windows. No man has a right to bring up his children without surrounding them with books, if he has the means to buy them. It is a wrong to his family. He cheats them! Children learn to read by being in the presence of books. The love of knowledge comes with reading and grows upon it.”

“A real subjection is born mechanically from a fictitious relation [...] He who is subjected to a field of visibility, and who knows it, assumes responsibility for the constraints of power; he makes them play spontaneously upon himself; he inscribed in himself the power relation in which he simultaneously plays both roles; he becomes the principle of his own subjection.”
