### Famous quotes containing the words list of, list, notable and/or theories:

“The advice of their elders to young men is very apt to be as unreal as a *list of* the hundred best books.”

—Oliver Wendell Holmes, Jr. (1841–1935)

“I made a *list* of things I have

to remember and a *list*

of things I want to forget,

but I see they are the same *list*.”

—Linda Pastan (b. 1932)

“Every *notable* advance in technique or organization has to be paid for, and in most cases the debit is more or less equivalent to the credit. Except of course when it’s more than equivalent, as it has been with universal education, for example, or wireless, or these damned aeroplanes. In which case, of course, your progress is a step backwards and downwards.”

—Aldous Huxley (1894–1963)

“Whatever practical people may say, this world is, after all, absolutely governed by ideas, and very often by the wildest and most hypothetical ideas. It is a matter of the very greatest importance that our *theories* of things that seem a long way apart from our daily lives, should be as far as possible true, and as far as possible removed from error.”

—Thomas Henry Huxley (1825–95)
