“Regardless of how secure a communication line is and how unbreakable a cryptographic algorithm seems to be, the weak links are often the endpoints - the sender (before encryption) and the recipient (after decryption) - unless they are code talkers using a language more obscure than Navajo.”

“He starts to break and seeing him start to break makes me start to break and I don't want that. He steps forward and puts his arms around me and he hugs me and I hug him and it feels good and strong and pure and real. This is my Brother, my Blood, the only thing in this World created from which I am created from, the Person in this World who knows me best, the Person who would miss me most if I was gone. That he cared enough to come here and that he cares enough to nearly break in front of me means something, but in the end, I know that it means only so much.”

“The devil himself is not inspired. He's the master of imitation, I don't think he can succeed in inspiring anyone too.”

Mwanandeke Kindembo (1996) Congolese author

“A man who lies to himself, and believes his own lies, becomes unable to recognize truth, either in himself or in anyone else, and he ends up losing respect for himself and for others. When he has no respect for anyone, he can no longer love, and in him, he yields to his impulses, indulges in the lowest form of pleasure, and behaves in the end like an animal in satisfying his vices. And it all comes from lying — to others and to yourself.”

Fyodor Dostoyevsky (1821–1881) Russian author

Variant translations:
Above all, do not lie to yourself. A man who lies to himself and listens to his own lie comes to a point where he does not discern any truth either in himself or anywhere around him, and thus falls into disrespect towards himself and others. Not respecting anyone, he ceases to love, and having no love, he gives himself up to passions and coarse pleasures, in order to occupy and amuse himself, and in his vices reaches complete bestiality, and it all comes from lying continually to others and to himself. A man who lies to himself is often the first to take offense. It sometimes feels very good to take offense, doesn't it? And surely he knows that no one has offended him, and that he himself has invented the offense and told lies just for the beauty of it, that he has exaggerated for the sake of effect, that he has picked on a word and made a mountain out of a pea — he knows all of that, and still he is the first to take offense, he likes feeling offended, it gives him great pleasure, and thus he reaches the point of real hostility… Do get up from your knees and sit down, I beg you, these posturings are false, too.

“It is impossible for anyone to be responsible for another person's behavior. The most you or any leader can do is to encourage each one to be responsible for himself.”

Robert A. Heinlein (1907–1988) American science fiction author

“The question what to believe is perhaps the most momentous that anyone can put to himself. Our beliefs are not to be classed among the luxuries, but among the necessaries of existence.”

Felix Adler (1851–1933) German American professor of political and social ethics, rationalist, and lecturer

Section 9 : Ethical Outlook
Founding Address (1876), Life and Destiny (1913)
Context: The question what to believe is perhaps the most momentous that anyone can put to himself. Our beliefs are not to be classed among the luxuries, but among the necessaries of existence. They become particularly important in times of trouble. They are like the life-boats carried by ocean ships. As long as the sea is smooth and there is every appearance of a prosperous voyage, the passengers seldom take note of the boats or inquire into their sea-worthiness. But when the storm breaks and danger approaches, then the capacity of the boats and their soundness become matters of the first importance.
