The ideas of right and wrong change with the experience of the race, and this change is wrought by the gradual ascertaining of consequences - of results.
Robert Green IngersollThe most important thing in this world is liberty. More important than food or clothes - more important than gold or houses or lands - more important than art or science - more important than all religions, is the liberty of man.
Robert Green IngersollYears should not be devoted to the acquisition of dead languages or to the study of history which, for the most part, is a detailed account of things that never occurred. It is useless to fill the individual with dates of great battles, with the births and deaths of kings. They should be taught the philosophy of history, the growth of nations, of philosophies, theories, and, above all, of the sciences.
