Exertion/physical

Famous quotes containing the words exertion and/or physical:

“From exertion come wisdom and purity; from sloth ignorance and sensuality.”
—Henry David Thoreau (1817–1862)

“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (1895–1985)
