Alfred Marshall

“The most valuable of all capital is that invested in human beings.”

“Political Economy or Economics is a study of mankind in the ordinary business of life.”

“The forces of supply and demand are like the two blades of a pair of scissors.”

“The economist, like everyone else, must concern himself with the ultimate aims of man.”

“Capital is that part of wealth which is devoted to obtaining further wealth.”

“Cool heads and warm hearts are required for economic endeavour.”

“The study of the causes of poverty is the study of the causes of the degradation of a large part of mankind.”

“A man is not likely to be a good economist if he is nothing else.”

“Knowledge is our most powerful engine of production.”

“The price of everything rises and falls from time to time and place to place; and with every such change the purchasing power of money is altered.”

“All wealth consists of desirable things... but not all desirable things are reckoned as wealth.”

“The Mecca of the economist lies in economic biology rather than in economic dynamics.”

“Nature's action is complex: and nothing is gained in the long run by pretending that it is simple.”
