International Celestial Reference

Famous quotes containing the words celestial and/or reference:

“We have reason to be grateful for celestial phenomena, for they chiefly answer to the ideal in man.”
—Henry David Thoreau (1817–1862)

“If we define a sign as an exact reference, it must include symbol because a symbol is an exact reference too. The difference seems to be that a sign is an exact reference to something definite and a symbol an exact reference to something indefinite.”
—William York Tindall (1903–1981)
