“The ideas which now pass for brilliant innovations and advances are in fact mere revivals of ancient errors, and a further proof of the dictum that those who are ignorant of the past are condemned to repeat it.”

“There are men regarded today as brilliant economists, who deprecate saving and recommend squandering on a national scale as the way of economic salvation; and when anyone points to what the consequences of these policies will be in the long run, they reply flippantly, as might the prodigal son of a warning father: "In the long run we are all dead." And such shallow wisecracks pass as devastating epigrams and the ripest wisdom.”

“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.”

“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.”

“The art of economics consists in looking not merely at the immediate but at the longer effects of any act or policy; it consists in tracing the consequences of that policy not merely for one group but for all groups.”

“It is significant that while there is a word "profiteer" to stigmatize those who make allegedly excessive profits, there is no such word as "wageer" - or "losseer.”

“Mere inflation-that is, the mere issuance of more money, with the consequence of higher wages and prices-may look like the creation of more demand. But in terms of the actual production and exchange of real things it is not.”
