“While it was long possible and sometimes tempting for physicists to deny the usefulness of the molecular hypothesis, we economists have the good luck of being some of the ‘molecules’ of economic life ourselves, and of having the possibility through human contacts to study the behavior of other ‘molecules’.”

— Tjalling Koopmans

“We all wear some disguise — make some professions — use some artifice to set ourselves off as being better than we are; and yet it is not denied that we have some good intentions and praiseworthy qualities at bottom, though we may endeavour to keep some others that we think less to our credit as much as possible in the background…”

“It is clearly absurd to say that if you go on adding atoms together until they have fused into a complex molecule, that molecule will become capable of self-reproduction. It is like saying that a skyscraper is more capable of reproduction than a bungalow. And suppose life did come into being through some accidental interaction of molecules, sun and cosmic rays; why should it not be content to rest passively? Why should it have been possessed of a desire to persist and evolve?”

“I can see no practical application of molecular biology to human affairs… DNA is a tangled mass of linear molecules in which the informational content is quite inaccessible.”

“I believe in the goodness of fellow human beings. We have a true desire for greatness and genuine good intention to be helpful to others. That's enough. Change is possible.”

“Economics is a science which studies human behavior as a relationship between ends and scarce means which have alternative uses.”

Lionel Robbins (1898–1984) British economist

An Essay on the nature and significance of Economic Science (1932), Chapter I: The Subject Matter of Economics
Context: The economist studies the disposal of scarce means. He is interested in the way different degrees of scarcity of different goods give rise to different ratios of valuation between them, and he is interested in the way in which changes in conditions of scarcity, whether coming from changes in ends or changes in means—from the demand side or the supply side—affect these ratios. Economics is a science which studies human behavior as a relationship between ends and scarce means which have alternative uses.

“I have not the smallest molecule of faith in aerial navigation other than ballooning”

William Thomson (1824–1907) British physicist and engineer

As a response to Major B. F. S. Baden Powell's request to join the Aeronautical Society, December 8, 1896 http://zapatopi.net/kelvin/papers/letters.html#baden-powell.

Context: I am afraid I am not in the flight for “aerial navigation”. I was greatly interested in your work with kites; but I have not the smallest molecule of faith in aerial navigation other than ballooning or of expectation of good results from any of the trials we hear of. So you will understand that I would not care to be a member of the aëronautical Society.

“From the beginning I could not believe that the “efficient market” hypothesis was dependent on a pure Brownian motion white noise or any truly random random walk. Place a minuscule colloidal molecule on a horizontal table that covers unlimited acres. Bombard it from every direction with thousands of minute atoms; and then if you wait long enough that original molecule can have traveled a billion miles in one direction. That’s truly a random Bachelier-Einstein walk, but not my notion of economic fluctuations.”

“I think if we study the primates, we notice that a lot of these things that we value in ourselves, such as human morality, have a connection with primate behavior.”

Jane Goodall (1934) British primatologist, ethologist, and anthropologist

Frans de Waal, in a NOVA interview, " The Bonobo in All of Us" PBS (1 January 2007) http://www.pbs.org/wgbh/nova/nature/bonobo-all-us.html; quotes from this interview were for some time misplaced on this page, which probably generated similar misattributions elsewhere, and the misplacement was not discovered until after this quotation had been selected for Quote of the Day, as a quote of Goodall. Corrections were subsequently made here, during the day the quote was posted as QOTD.

Context: I think if we study the primates, we notice that a lot of these things that we value in ourselves, such as human morality, have a connection with primate behavior. This completely changes the perspective, if you start thinking that actually we tap into our biological resources to become moral beings. That gives a completely different view of ourselves than this nasty selfish-gene type view that has been promoted for the last 25 years.
