Famous quotes containing the words modern, theories and/or present:
“Bureacracy, the rule of no one, has become the modern form of despotism.”
—Mary McCarthy (1912–1989)
“The theories and speculations of men concern us more than their puny accomplishment. It is with a certain coldness and languor that we loiter about the actual and so-called practical.”
—Henry David Thoreau (1817–1862)
“As regards the celebrated “struggle for life,” it seems to me for the present to have been rather asserted than proved. It does occur, but as the exception; the general aspect of life is not hunger and distress, but rather wealth, luxury, even absurd prodigality—where there is a struggle it is a struggle for power.”
—Friedrich Nietzsche (1844–1900)
