Full Price Equation
The simple Price equation was based on the assumption that the characters zi do not change over one generation. If it is assumed that they do change, with zi being the value of the character in the child population, then the full Price equation must be used. A change in character can come about in a number of ways. The following two examples illustrate two such possibilities, each of which introduces new insight into the Price equation.

Famous quotes containing the words full, price and/or equation:
“The right honourable gentleman caught the Whigs bathing, and walked away with their clothes. He has left them in the full enjoyment of their liberal positions, and he is himself a strict conservative of their garments.”
—Benjamin Disraeli (1804–1881)
“To me a book is a message from the gods to mankind; or, if not, should never be published at all.... A message from the gods should be delivered at once. It is damnably blasphemous to talk about the autumn season and so on. How dare the author or publisher demand a price for doing his duty, the highest and most honourable to which a man can be called?”
—Aleister Crowley (1875–1947)
“Jail sentences have many functions, but one is surely to send a message about what our society abhors and what it values. This week, the equation was twofold: female infidelity twice as bad as male abuse, the life of a woman half as valuable as that of a man. The killing of the woman taken in adultery has a long history and survives today in many cultures. One of those is our own.”
—Anna Quindlen (b. 1952)
