“And I thought of the Transit of Venus: that though the bodies be vast and distant, and their motions occult, their hesitations retrograde, one could, I thought, with exceeding care and preparation, observe, and in their distance, know them, triangulate to arrive at the ambits of their motivation; and that in this calculation alone, one might banish uncertainty, and know at last what constituted other bodies, and how small the gulf that lies between us all.”

“The infinite distance between body and mind symbolizes the infinitely more infinite distance between mind and charity, for charity is supernatural....Out of all bodies together we could not succeed in creating one little thought. It is impossible, and of a different order. Out of all bodies and minds we could not extract one impulse of true charity. It is impossible, and of a different, supernatural, order.”

“I have always hesitated to give advice, for how can one advise another how to act unless one knows that other as well as one knows himself? Heaven knows. I know little enough of myself: I know nothing of others. We can only guess at the thoughts and emotions of our neighbours. Each one of us is a prisoner in a solitary tower and he communicates with the other prisoners, who form mankind, by conventional signs that have not quite the same meaning for them as for himself.”

“The gulf between the information we proclaim & the information we know to be true is vast. In other words: we say one thing & do another.”

“I can calculate the motion of heavenly bodies but not the madness of people.”

“I had thought about everything carefully before I had agreed to him. I had made every preparation, every calculation, except for those two essentials that could not be calculated; his heart and mine.”
