Famous quotes containing the words work, energy and/or principle:
“Women have entered the work force . . . partly to express their feelings of self-worth . . . partly because today many families would not survive without two incomes, partly because they are not at all sure their marriages will last. The day of the husband as permanent meal-ticket is over, a fact most women recognize, however they feel about “women’s liberation.””

“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“Custom, then, is the great guide of human life. It is that principle alone, which renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past.”
—David Hume (1711–1776)
