Thomas Cahill quote: “Human beings never know more than a part, as "through a glass darkly"; and all knowledge comes to us in pieces.”

“Human understanding is fallible, and we see through a glass, darkly. Any religion is a shadow of God. But the shadows of God are not God.”

Margaret Atwood book The Year of the Flood

“For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. And now abideth faith, hope, charity, these three; but the greatest of these is charity.”

Paul of Tarsus book First Epistle to the Corinthians

I Corinthians Ch. 13 (KJV) The word "Charity" is here used as a translation of the Latin Caritas, and the original Greek Agape, which were words for "Love", and used to denote the highest and most self-transcending forms of Love.
Variants: Though I speak with the tongues of men and of angels, but have not love, I have become sounding brass or a clanging cymbal. And though I have the gift of prophecy, and understand all mysteries and all knowledge, and though I have all faith, so that I could remove mountains, but have not love, I am nothing. And though I bestow all my goods to feed the poor, and though I give my body to be burned, but have not love, it profits me nothing.
Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up; does not behave rudely, does not seek its own, is not provoked, thinks no evil; does not rejoice in iniquity, but rejoices in the truth; bears all things, believes all things, hopes all things, endures all things.
Love never fails. But whether there are prophecies, they will fail; whether there are tongues, they will cease; whether there is knowledge, it will vanish away. For we know in part and we prophesy in part. But when that which is perfect has come, then that which is in part will be done away.
When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things. For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known.
And now abide faith, hope, love, these three; but the greatest of these is love.
I Corinthians Ch. 13 (NKJV)
If I speak in human and angelic tongues but do not have love, I am a resounding gong or a clashing cymbal. And if I have the gift of prophesy and comprehend all mysteries and all knowledge; if I have all faith so as to move mountains but do not have love, I am nothing. If I give away everything I own, and if I hand my body over so that I may boast but do not have love, I gain nothing.
Love is patient, love is kind. It is not jealous, [love] is not pompous, it is not inflated, it is not rude, it does not seek its own interests, it is not quick-tempered, it does not brood over injury, it does not rejoice over wrongdoing but rejoices with the truth. It bears all things, believes in all things, hopes all things, endures all things.
Love never fails. If there are prophecies, they will be brought to nothing; if tounges, they will cease; if knowledge, it will be brought to nothing. For we know partially and we prophesy partially, but when the perfect comes, the partial will pass away. When I was a child, I used to talk as a child, think as a child, reason as a child; when I became a man, I put aside childish things. At present, we see indistinctly, as in a mirror, but then face to face. At present I know partially; then I shall know fully, as I am fully known. So faith, hope, love remain, these three; but the greatest of these is love.
1 Corinthians Ch. 13 (NASB)
Now, there remain faith, hope, love, these three; but the greatest of these is love.

First Epistle to the Corinthians
Context: Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing. And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing. Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up, Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; Rejoiceth not in iniquity, but rejoiceth in the truth; Beareth all things, believeth all things, hopeth all things, endureth all things.
Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away.
When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. And now abideth faith, hope, charity, these three; but the greatest of these is charity.

“Even in ordinary times there are very few of us who do not see the problems of life as through a glass, darkly; and when the glass is clouded by the murk of furious popular passion, the vision of the best and the bravest is dimmed.”

Theodore Roosevelt (1858–1919) American politician, 26th president of the United States

1910s, The New Nationalism (1910)

“So as through a glass, and darkly
The age long strife I see
Where I fought in many guises,
Many names, but always me.”

George S. Patton (1885–1945) United States Army general

Through A Glass, Darkly (1918)
Context: So as through a glass, and darkly
The age long strife I see
Where I fought in many guises,
Many names, but always me. And I see not in my blindness
What the objects were I wrought,
But as God rules o'er our bickerings
It was through His will I fought. So forever in the future,
Shall I battle as of yore,
Dying to be born a fighter,
But to die again, once more.

“All great qualities are never found in any one man or in any one race. The whole of humanity, like the whole of everything else, is ever greater than a part. Men only know themselves by knowing others, and contact is essential to this knowledge”

Frederick Douglass (1818–1895) American social reformer, orator, writer and statesman

1860s, Our Composite Nationality (1869)
Context: The theory that each race of men has some special faculty, some peculiar gift or quality of mind or heart, needed to the perfection and happiness of the whole is a broad and beneficent theory, and, besides its beneficence, has, in its support, the voice of experience. Nobody doubts this theory when applied to animals or plants, and no one can show that it is not equally true when applied to races. All great qualities are never found in any one man or in any one race. The whole of humanity, like the whole of everything else, is ever greater than a part. Men only know themselves by knowing others, and contact is essential to this knowledge. In one race we perceive the predominance of imagination; in another, like the Chinese, we remark its almost total absence. In one people we have the reasoning faculty; in another the genius for music; in another exists courage, in another great physical vigor, and so on through the whole list of human qualities. All are needed to temper, modify, round and complete the whole man and the whole nation.

“In the long arcade of the bus station footfalls come back like laughter. He marches darkly toward his darkly marching shape in the glass of the depot door. His fetch come up from life's other side like an autoscopic hallucination, Suttree and Antisuttree, hand reaching to the hand.”

Cormac McCarthy book Suttree

“The fact that we are human beings is infinitely more important than all the peculiarities that distinguish human beings from one another; it is never the given that confers superiorities: "virtue", as the ancients called it, is defined at the level of "that which depends on us."”

Simone de Beauvoir book The Second Sex

In both sexes is played out the same drama of the flesh and the spirit, of finitude and transcendence; both are gnawed away by time and laid in wait for by death, they have the same essential need for one another; and they can gain from their liberty the same glory. If they were to taste it, they would no longer be tempted to dispute fallacious privileges, and fraternity between them could then come into existence.
