Do you see this egg? With this you can topple every theological theory, every church or temple in the world.
— Denis Diderot

All schools, all colleges, have two great functions: to confer, and to conceal, valuable knowledge. The theological knowledge which they conceal cannot justly be regarded as less valuable than that which they reveal. That is, when a man is buying a basket of strawberries it can profit him to know that the bottom half of it is rotten.
Mark Twain theological quote

We cannot look at the child who has been raped and offer the theological maxim that God will draw something good from out of this. We cannot think of the children consumed by the fires of Auschwitz and Hiroshima and manufacture some easy gratitude. Gratitude does not take away the horrors of violence.
— Ellen Vaughn

Each department of knowledge passes through three stages. The theoretic stage; the theological stage and the metaphysical or abstract stage.
— Auguste Comte

Our own theological Church, as we know, has scorned and vilified the body till it has seemed almost a reproach and a shame to have one, yet at the same time has credited it with power to drag the soul to perdition.
— Eliza Farnham
