Famous quotes containing the word observances:
“... if it be true that death is annihilation, then the man who believes that he will certainly go straight to heaven when he dies, provided he has fulfilled certain simply observances in this life, has a cheap pleasure which will not be followed by the least disappointment.”
—Charles Sanders Peirce (1839–1914)
