„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’.“

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

—  Lionel Robbins British economist 1898 - 1984

An Essay on the nature and significance of Economic Science (1932), Chapter I: The Subject Matter of Economics
Contexto: 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 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 British primatologist, ethologist, and anthropologist 1934

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.
Contexto: 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.

„What I am trying to do is to present a unified scientific view of life; that is, a view integrating life's biological, cognitive, and social dimensions. I have had many discussions with social scientists, cognitive scientists, physicists and biologist who question that task, who said that this would not be possible. They ask, why do I believe that I can do that? My belief is based largely on our knowledge of evolution. When you study evolution, you see that there was, first of all, evolution before the appearance of life, there was a molecular type of evolution where structures of greater and greater complexity evolved out of simple molecules. Biochemist who study that have made tremendous progress in understanding that process of molecular evolution. Then we had the appearance of the first cell which was a bacterium. Bacteria evolved for about 2 billion years and in doing so invented, if you want to use the term, or created most of the life processes that we know today. Biochemical processes like fermentation, oxygen breathing, photosynthesis, also rapid motion, were developed by bacteria in evolution. And what happened then was that bacteria combined with one another to produce larger cells — the so-called eukaryotic cells, which have a nucleus, chromosomes, organelles, and so on. This symbiosis that led to new forms is called symbiogenesis.“
