Famous quotes containing the words conditions, affecting, small and/or intestine:
“There is no society known where a more or less developed criminality is not found under different forms. No people exists whose morality is not daily infringed upon.

—Emile Durkheim (1858–1917)
“Children must eventually train their own children, and any impoverishment of their impulse life, for the sake of avoiding friction, must be considered a possible liability affecting more than one lifetime”
—Erik H. Erikson (20th century)
“To a small man every greater is an exaggeration.”
—Henry David Thoreau (1817–1862)
