“The third reason capitalism gets blame here is that alternative systems—those not driven by a profit-first logic—could manage viruses better. While not profitable to produce and stockpile everything needed for a viral pandemic, it is efficient. The wealth already lost in this pandemic far exceeds the cost to have produced and stockpiled the tests and ventilators, the lack of which is contributing so much to today's disaster. Capitalism often pursues profit at the expense of more urgent social needs and values. In this, capitalism is grossly inefficient. This pandemic is now bringing that truth home to people.”

“Few people seem to perceive fully as yet that the most far-reaching consequence of the establishment of the common origin of all species is ethical; that it logically involved a readjustment of altruistic morals, by enlarging, as a necessity of rightness, the application of what has been called the 'Golden Rule' from the area of mere mankind to that of the whole animal kingdom. Possibly Darwin himself did not quite perceive it. While man was deemed to be a creation apart from all other creations, a secondary or tertiary morality was considered good enough to practise towards the 'inferior' races; but no person who reasons nowadays can escape the trying conclusion that this is not maintainable. And though we may not at present see how the principle of equal justice all round is to be carried out in it entirety, I recognize that the League is grappling with the question.”

“We have become blind to the alternatives to violence. This involves us in a sort of official madness, in which, while following what seems to be a perfect logic of self-defense and deterrence, we commit one absurdity after another: We seek to preserve peace by fighting a war, or to advance freedom by subsidizing dictatorships, or to "win the hearts and minds of the people" by poisoning their crops and burning their villages and confining them in concentration camps; we seek to uphold the "truth" of our cause with lies, or to answer conscientious dissent with threats and slurs and intimidations. … I have come to the realization that I can no longer imagine a war that I would believe to be either useful or necessary. I would be against any war.”

“The false logic involved is: “We exist; therefore something—call it X—created us.””

Arthur C. Clarke book Crusade

Once this assumption is made, the properties of the hypothetical X can be fantasied in an unlimited number of ways.
But the entire process is obviously fallacious; for by the same logic something must have created X—and so on. We are immediately involved in an infinite regress, which can have no meaning in the real universe.

“True love has be-guided me, O friend!
Reveal to me the land of my Beloved.
At my parents' I was an innocent maid.
With love to me He has robbed me of my heart.
Logic, semantics and a store of knowledge—
Such pedantry has left me devoid of Him.
Of what use are fasts and prayers to them,
Who have drunk deep from the front of love?
Sitting in the company of the Spouse,
Bullah is free from all rituals, O friend!”

“Unless the intensity of our defense of life matches the ferocity of the assault against it, we allow a greater violence to grow exponentially until an earth once teeming with life becomes a mass graveyard, a battered wasteland, and a toxic cesspool. Then, when it is finally too late, the unfortunates who remain will grasp what the radicals tried to convey: what the logic of growth and capitalism finally wrought, the colossal failure of human vision and will, and the complicity of pacifism with the greatest violence of all.”

“However, efilism's claim that all life, human and non-human, should be ceased is a hubris I am not convinced humans have a right to exert. While the cessation of suffering humans cause is already manipulated in a way that could come under an efilist rubric, these 'management' tools usually come in the form of culling populations of nonhumans to redress an imagined environmental balance most usually caused by humans in the first place. Domestic efilism such a neutering rescue animals is necessary, especially when rescuing can involve the speciesism of feeding one slaughtered animal to sustain another, and neutering humans is the logical way to prevent the perpetuation of this practice as well”

“You talk of Paine with more respect than he deserves: He is utterly incapable of comprehending his subject. He has not even a moderate portion of learning of any kind. He has learnd the instrumental part of literature, a style, and a method of disposing his ideas, without having ever made a previous preparation of Study or thinking—for the use of it. ... [Paine] possesses nothing more than what a man whose audacity makes him careless of logical consequences, and his total want of honour and morality makes indifferent as to political consequences, may very easily write.

“Western civilization, it seems to me, stands by two great heritages. One is the scientific spirit of adventure — the adventure into the unknown, an unknown which must be recognized as being unknown in order to be explored; the demand that the unanswerable mysteries of the universe remain unanswered; the attitude that all is uncertain; to summarize it — the humility of the intellect. The other great heritage is Christian ethics — the basis of action on love, the brotherhood of all men, the value of the individual — the humility of the spirit.
These two heritages are logically, thoroughly consistent. But logic is not all; one needs one's heart to follow an idea. If people are going back to religion, what are they going back to? Is the modern church a place to give comfort to a man who doubts God — more, one who disbelieves in God? Is the modern church a place to give comfort and encouragement to the value of such doubts? So far, have we not drawn strength and comfort to maintain the one or the other of these consistent heritages in a way which attacks the values of the other? Is this unavoidable? How can we draw inspiration to support these two pillars of western civilization so that they may stand together in full vigor, mutually unafraid? Is this not the central problem of our time?”

“In any society built on institutionalized racism, race-mixing doesn't merely challenge the system as unjust, it reveals the system as unsustainable and incoherent. Race-mixing proves that races can mix - and in a lot of cases, want to mix. Because a mixed person embodies that rebuke to the logic of the system, race-mixing becomes a crime worse than treason.”

“I suggest that scientific knowledge, though logically more articulate and far more complex, is of this sort. The books and teachers from whom it is acquired present concrete examples together with a multitude of theoretical generalizations. Both are essential carriers of knowledge, and it is therefore Pickwickian to seek a methodological criterion that supposes the scientist can specify in advance whether each imaginable instance fits or would falsify his theory.”

“Mystery is a word with no objective pertinence, merely describing the limitations of a mind. In fact, a mind may be classified by the order of the phenomena it considers mysterious.… The mystery is resolved, the solution made known. “Of course, it is obvious!” comes the chorus. A word about the obvious: it is always obvious.… The common mind transposed the sequence, letting the mystery generate the solution. This is logic in reverse; actually the mystery relates to the solution as the foam relates to the beer.…”

“The real significance of the Russell paradox, from the standpoint of the modal-logic picture, is this: it shows that no concrete structure can be a standard model for the naive conception of the totality of all sets; for any concrete structure has a possible extension that contains more 'sets.'”

Context: (If we identify sets with the points that represent them in the various possible concrete structures, we might say: it is not possible for all possible sets to exist in any one world!) Yet set theory does not become impossible. Rather, set theory becomes the study of what must hold in, e.g. any standard model for Zermelo set theory.

“Because physical theories typically predict numerical values, an improvement in experimental precision reduces the tolerance range and hence increases corroborability. In most psychological research, improved power of a statistical design leads to a prior probability approaching ½ of finding a significant difference in the theoretically predicted direction. Hence the corroboration yielded by "success" is very weak, and becomes weaker with increased precision. "Statistical significance" plays a logical role in psychology precisely the reverse of its role in physics. This problem is worsened by certain unhealthy tendencies prevalent among psychologists, such as a premium placed on experimental "cuteness" and a free reliance upon ad hoc explanations to avoid refutation.”
