White people owe it quite as much to themselves as to the colored race to treat well the colored man who shows by his life that he deserves such treatment; for it is surely the highest wisdom to encourage in the colored race all those individuals who are honest, industrious, law-abiding, and who therefore make good and safe neighbors and citizens.
 Theodore Roosevelt, State of the Union Address. copy citation

Context

“it is the same rule that must be applied in dealing with rich men and poor men; that is, to treat each man, whatever his color, his creed, or his social position, with even-handed justice on his real worth as a man. White people owe it quite as much to themselves as to the colored race to treat well the colored man who shows by his life that he deserves such treatment; for it is surely the highest wisdom to encourage in the colored race all those individuals who are honest, industrious, law-abiding, and who therefore make good and safe neighbors and citizens. Reward or punish the individual on his merits as an individual. Evil will surely come in the end to both races if we substitute for this just rule the habit of treating all the members of the race, good and bad, alike.” source
