“We must recognize that beneath the superficial classifications of sex and race the same potentialities exist, recurring generation after generation, only to perish because society has no place for them.”

Literary and Historical Miscellanies (1855), The Necessity, the Reality, and the Promise of the Progress of the Human Race (1854)
Context: No science has been reached, no thought generated, no truth discovered, which has not from all time existed potentially in every human mind. The belief in the progress of the race does not, therefore, spring from the supposed possibility of his acquiring new faculties, or coming into the possession of a new nature.
Still less does truth vary. They speak falsely who say that truth is the daughter of time; it is the child of eternity, and as old as the Divine mind. The perception of it takes place in the order of time; truth itself knows nothing of the succession of ages. Neither does morality need to perfect itself; it is what it always has been, and always will be. Its distinctions are older than the sea or the dry land, than the earth or the sun. The relation of good to evil is from the beginning, and is unalterable.

From Nothing Personal, a collaboration with the photographer Richard Avedon (1964). Baldwin's text for the volume can be found " here https://scholarworks.umass.edu/cgi/viewcontent.cgi?article=1042&context=cibs".
Context: One must say Yes to life, and embrace it wherever it is found - and it is found in terrible places. … For nothing is fixed, forever and forever, it is not fixed; the earth is always shifting, the light is always changing, the sea does not cease to grind down rock. Generations do not cease to be born, and we are responsible to them because we are the only witnesses they have. The sea rises, the light fails, lovers cling to each other and children cling to us. The moment we cease to hold each other, the moment we break faith with one another, the sea engulfs us and the light goes out.

1910s, The New Nationalism (1910)
Context: Conservation means development as much as it does protection. I recognize the right and duty of this generation to develop and use the natural resources of our land; but I do not recognize the right to waste them, or to rob, by wasteful use, the generations that come after us. I ask nothing of the nation except that it so behave as each farmer here behaves with reference to his own children. That farmer is a poor creature who skins the land and leaves it worthless to his children. The farmer is a good farmer who, having enabled the land to support himself and to provide for the education of his children, leaves it to them a little better than he found it himself. I believe the same thing of a nation.

Prologue
The Path of the King (1921)
Context: Generations follow, oblivious of the high beginnings, but there is that in the stock which is fated to endure. The sons and daughters blunder and sin and perish, but the race goes on, for there is a fierce stuff of life in it. It sinks and rises again and blossoms at haphazard into virtue or vice, since the ordinary moral laws do not concern its mission. Some rags of greatness always cling to it, the dumb faith that sometime and somehow that blood drawn from kings it never knew will be royal again. Though nature is wasteful of material things, there is no waste of spirit. And then after long years there comes, unheralded and unlooked-for, the day of the Appointed Time...
