Epictetus/influence/acting

Famous quotes containing the words influence and/or acting:

“It behooves every man to see that his influence is on the side of justice, and let the courts make their own characters.”
—Henry David Thoreau (1817–1862)

“It would be easy ... to regard the whole of world 3 as timeless, as Plato suggested of his world of Forms or Ideas.... I propose a different view—one which, I have found, is surprisingly fruitful. I regard world 3 as being essentially the product of the human mind.... More precisely, I regard the world 3 of problems, theories, and critical arguments as one of the results of the evolution of human language, and as acting back on this evolution.”
—Karl Popper (1902–1994)
