Bruce Lee quote: “The More we value things, the less we value ourselves”

“It is not true that on an exchange of commodities we give value for value. On the contrary, each of the two contracting parties in every case, gives a less for a greater value. … If we really exchanged equal values, neither party could make a profit. And yet, they both gain, or ought to gain. Why? The value of a thing consists solely in its relation to our wants. What is more to the one is less to the other, and vice versa. … It is not to be assumed that we offer for sale articles required for our own consumption. … We wish to part with a useless thing, in order to get one that we need; we want to give less for more. … It was natural to think that, in an exchange, value was given for value, whenever each of the articles exchanged was of equal value with the same quantity of gold. … But there is another point to be considered in our calculation. The question is, whether we both exchange something superfluous for something necessary.”

Étienne Bonnot de Condillac (1714–1780) French academic

“We are delighted to find a person who values us as we value ourselves, and distinguishes us from the rest of mankind, with an attention not unlike that with which we distinguish ourselves.”

“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.
