1930s, My Credo (1932)
Context: Our situation on this earth seems strange. Every one of us appears here involuntarily and uninvited for a short stay, without knowing the whys and the wherefore. In our daily lives we only feel that man is here for the sake of others, for those whom we love and for many other beings whose fate is connected with our own. I am often worried at the thought that my life is based to such a large extent on the work of my fellow human beings and I am aware of my great indebtedness to them.

Introduction to the "Corners on the Curving Sky" section of the book Soulscript (1970) compiled by Jordan. These lines have been widely published in verse format as work misattributed to Gwendolyn Brooks, usually as a poem titled "Corners on the Curving Sky." One website http://web.archive.org/20090809112040/www.geocities.com/juscurious/anon.html indicated that Brooks had publicly repudiated the attribution of these lines to her, but the misattribution seems to have long remained largely unrecognized.
Context: Our earth is round, and, among other things, that means that you and I can hold completely different points of view and both be right. The difference of our positions will show stars in your window I cannot even imagine. Your sky may burn with light, while mine, at the same moment, spreads beautiful to darkness. Still we must choose how we separately corner the circling universe of our experience. Once chosen, our cornering will determine the message of any star and darkness we encounter. These poems speak to philosophy; they reveal the corners where we organize what we know.

The above statements have been widely published in the above format as lines of verse attributed to Brooks, usually as a poem titled "Corners on the Curving Sky" — but one website http://web.archive.org/20090809112040/www.geocities.com/juscurious/anon.html indicated that she declared she did not write them. The words actually occur as an introduction to the "Corners on the Curving Sky" section of the book Soulscript (1970) compiled by June Jordan, in which other poems of Brooks were included, and thus is apparently the work of Jordan. It appears simply in paragraph form and reads thus:
Misattributed, "Corners on the Curving Sky"
Context: Our earth is round, and, among other things
That means that you and I can hold completely different
Points of view and both be right.
The difference of our positions will show
Stars in your window I cannot even imagine.
Your sky may burn with light,
While mine, at the same moment,
Spreads beautiful to darkness.

Letter to (22 August 1774), as published in The Life of John Jay (1833) by William Jay, Vol. 2, p. 345.
1770s, Letter to Lindley Murray (1774)
Context: Among the strange things of this world, nothing seems more strange than that men pursuing happiness should knowingly quit the right and take a wrong road, and frequently do what their judgments neither approve nor prefer. Yet so is the fact; and this fact points strongly to the necessity of our being healed, or restored, or regenerated by a power more energetic than any of those which properly belong to the human mind.
We perceive that a great breach has been made in the moral and physical systems by the introduction of moral and physical evil; how or why, we know not; so, however, it is, and it certainly seems proper that this breach should be closed and order restored. For this purpose only one adequate plan has ever appeared in the world, and that is the Christian dispensation. In this plan I have full faith. Man, in his present state, appears to be a degraded creature; his best gold is mixed with dross, and his best motives are very far from being pure and free from earth and impurity.
