Hubert Selby Jr. quote: “He flowed deeper and deeper into himself, wrapped in the comforting strength of hate.”

“He knew that there was no quick comfort for emotions like those. They were deeper and they did not need to be told. They were felt.”

Lois Lowry book The Giver

Context: Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Hate multiplies hate, violence multiplies violence, and toughness multiplies toughness in a descending spiral of destruction.
Context: Let us move now from the practical how to the theoretical why: Why should we love our enemies? The first reason is fairly obvious. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Hate multiplies hate, violence multiplies violence, and toughness multiplies toughness in a descending spiral of destruction. So when Jesus says "love your enemies," he is setting forth a profound and ultimately inescapable admonition. Have we not come to such an impasse in the modern world that we must love our enemies-or else? The chain reaction of evil-Hate begetting hate, wars producing more wars-must be broken, or we shall be plunged into the dark abyss of annihilation.
Context: I mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even an enemy. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.

“Behind every specific call, whether it is to teach or preach or write or encourage or comfort, there is a deeper call that gives shape to the first: the call to give ourselves away - the call to die.”

“But it was too interesting, too new, too flattering, too deeply comforting to resist, it was a liberation to be in love and say so, and she could only let herself go deeper.”

Context: When next he came to me he was drunk—royally drunk on many poets for the first time revealed to him. His pupils were dilated, his words tumbled over each other, and he wrapped himself in quotations—as a beggar would enfold himself in the purple of emperors.

“The mind of man can never be wholly barren. Through our whole lives we are subject to successive impressions; for, either new ideas are continually flowing in, or traces of the old ones are marked deeper.”

Joseph Priestley book Institutes of Natural and Revealed Religion

Vol. I : The Dedication (March 1772)
Institutes of Natural and Revealed Religion (1772–1774)
Context: The mind of man can never be wholly barren. Through our whole lives we are subject to successive impressions; for, either new ideas are continually flowing in, or traces of the old ones are marked deeper. If, therefore, you be not acquiring good principles be assured that you are acquiring bad ones; if you be not forming virtuous habits you are, how insensibly soever to yourselves, forming vicious ones…
