The evolution of higher and of lower forms of life is as well and as soundly established as the eternal hills. It has long since ceased to be a theory; it is a law of Nature as universal in living things as is the law of gravitation in material things and in the motions of the heavenly spheres. - Henry Fairfield Osborn
To consult the rules of composition before making a picture is a little like consulting the law of gravitation before going for a walk. - Edward Weston
To be a saint is the exception; to be upright is the rule. Err, falter, sin, but be upright. To commit the least possible sin is the law for man. Sin is a gravitation. - Victor Hugo
Gravitation cannot be held responsible for people falling in love. - Albert Einstein
A true man never frets about his place in the world, but just slides into it by the gravitation of his nature, and swings there as easily as a star. - Edward Chapin
Gravitation is not responsible for people falling in love. - Albert Einstein
To commit the least possible sin is the law for man. To live without sin is the dream of an angel. Everything terrestrial is subject to sin. Sin is a gravitation. - Victor Hugo
