“Variability is the law of life, and as no two faces are the same, so no two bodies are alike, and no two individuals react alike and behave alike under the abnormal conditions which we know as disease.”
On the Educational Value of the Medical Society (1903)

“This course brings diseases and afflictions upon the body and soul alike.”
Source: Guide for the Perplexed (c. 1190), Part III, Ch.12
Context: The third class of evils comprise those which everyone causes to himself by his own action. This is the largest class, and is far more numerous than the second class. It is especially of these evils that all men complain,—only few men are found that do not sin against themselves by this kind of evil.... This class of evil originates in man's vices, such as excessive desire for eating, drinking, and love; indulgence in these things in undue measure, or in improper manner, or partaking of bad food. This course brings diseases and afflictions upon the body and soul alike.

The Liberty of Man, Woman and Child (1877)
Context: In the old times of which I have spoken, they desired to make all men think exactly alike. All the mechanical ingenuity of the world cannot make two clocks run exactly alike, and how are you going to make hundreds of millions of people, differing in brain and disposition, in education and aspiration, in conditions and surroundings, each clad in a living robe of passionate flesh — how are you going to make them think and feel alike? If there is an infinite god, one who made us, and wishes us to think alike, why did he give a spoonful of brains to one, and a magnificent intellectual development to another? Why is it that we have all degrees of intelligence, from orthodoxy to genius, if it was intended that all should think and feel alike?

“We ask to be recognized as men. We ask that the same law shall work alike on all men.”
Lincoln Hall Speech (1879)
Context: I know that my race must change. We cannot hold our own with the white men as we are. We only ask an even chance to live as other men live. We ask to be recognized as men. We ask that the same law shall work alike on all men. If an Indian breaks the law, punish him by the law. If a white man breaks the law, punish him also.

Cf. Anatole France, Le Lys Rouge [The Red Lily] (1894), ch. 7: La majestueuse égalité des lois, qui interdit au riche comme au pauvre de coucher sous les ponts, de mendier dans les rues et de voler du pain. (The law, in its majestic equality, forbids the rich as well as the poor to sleep under bridges, to beg in the streets, and to steal bread.)
