Many people have said to me that I’m a mystic. I find that a bit mysterious. I just use logic and common sense for my philosophies.

Marcuse's own highhanded scorn about those whom he criticizes makes it not inapposite to remark that the arguments which I have been deploying are very elementary ones, familiar to every student with the barest knowledge of logic. The suspicion is thus engendered that not only Marcuse but also Adorno and Horkheimer actually do not know any logic, and it is certainly the case that, if they do know any, all three have taken some pains to conceal their knowledge of the subject which they are professedly criticizing.

Mathematics is my first language.

Mathematical design is the future. Landscape Mathematics is the revolution!

Mathematics had never had more than a secondary interest for him [her husband, George Boole]; and even logic he cared for chiefly as a means of clearing the ground of doctrines imagined to be proved, by showing that the evidence on which they were supposed to give rest had no tendency to prove them.

May the Furies tear out my tongue if I ever argue philosophy again.

Mental health sufferers are not crazy. They have special insight. You better recognize that setting aside your interest people to stay asleep and show empathy towards God's imperfect creations, otherwise the world has no meaning to exist.

Mindless action without a real understanding of the ramifications is only likely to result in serious miscalculations or a colossal waste of time. Avoid both by using your judgment, filtered through both knowledge and experience. Use common sense and logic as a counterbalance to emotion.

Miracles define common sense.

Mock and ridicule men who refuse to use reason and logic; use reason and logic against men who know only how to mock and ridicule.

Monty Jones: Dad, is there a word to describe answers that are completely correct but entirely useless under the circumstances? Professor Jones: Yes, yes there is.

Most plans are critically flawed by their own logic. A failure at any step will ruin everything. That's just basic cause and effect. It's easy for a good plan to fall apart. Therefore, a plan that has no attachment to logic cannot be stopped. The success or failure of any step will have no impact on the macro level.

Most reject the more repugnant or indefensible dogmas while still holding onto some core belief. Many believers will proudly describe themselves as "reasonable" or "rational" based on how little of their religion they still embrace versus how much they now reject. I think it's funny when people realize that the less you believe the more reasonable you are, but they stop before they reach the logical conclusion.

Murder isn't the most logical way to escape a difficult situation. It only leads to a different difficult situation.

My Lord Bacon, in his Novum Organum, discusses this point, and investigates with his habitual brilliance the various categories of evidence, and finds them all flawed. None conveys certainty, he decides, a conclusion which (one might think) would be devastating for scientists and lawyers alike: historians and theologians have learned to live with this, the former modestly tempering their claims, the latter resting their glorious edifice on the more reliable foundations of revelation. For without certainty what is science except glorified guesswork? And without the conviction of certainty, total and absolute, how can we ever hang anyone with an easy conscience? Witnesses can lie and, as I know myself, even an innocent can confess a crime he did not commit. But Lord Bacon did not despair, and claimed one instance of a fingerpost which points in one direction only, and allows of no other possibility. The perfectly independent eyewitness, who has nothing to gain from his revelation, who is, in addition, schooled in observation and report through a gentlemanly status and education, this is the nearest we can get to a reliable witness and his testimony may be said to be conclusive, overwhelming all lesser forms.

My grandmother always told me: beauty fades but dumb is forever.

Music enables mind to compose things in the outer limit of logic.

My endeavour is to make everyone think creatively and logically! My endeavour is to let newness enter the world!

My head is a prison I’ve been locked in from the start, So if I'm treated like a criminal I might as well play the part. (attrib: E. Tancarville)

My heart pounded annoyingly in my ears, and it was getting harder to stay focused. I'd almost gotten trapped in here, and now I'd come back. Sometimes I did have truly terrible ideas.

Mythology was never designed to describe historically verifiable events that actually happened. It was an attempt to express their inner significance or to draw attention to realities that were too elusive to be discussed in a logically coherent way.

Nobody mentions it, but there are two types of insanity. One is the unstable mind, that's the one they make films about, the romantic insanity, a person out of control and capable of almost anything. But the other is the madness of the stable mind, where behaviour is illogical and damaging but every day it is exactly the same.

Needless to say, there are people who hate Arabs, Somalis, and other immigrants from predominantly Muslim societies for racist reasons. But if you can’t distinguish that sort of blind bigotry from a hatred and concern for dangerous, divisive, and irrational ideas—like a belief in martyrdom, or a notion of male “honor” that entails the virtual enslavement of women and girls—you are doing real harm to our public conversation. Everything I have ever said about Islam refers to the content and consequences of its doctrine. And, again, I have always emphasized that its primary victims are innocent Muslims—especially women and girls.

No, I'd better not speak of it. It's a secret for me alone, of vital importance for me, and not to be put into words. This new feeling has not changed me, has not made me happy and enlightened all of a sudden as I dreamed. Just like the feeling for my child, there was no surprise in this either. Faith—or not faith—I don't know what it is—but this feeling has come just as imperceptibly through suffering, and has taken firm root in my soul. I shall go on in the same way, losing my temper with Ivan the coachman, falling into angry discussions, expressing my opinions tactlessly. There will be still the same wall between the holy of holies of my soul and other people, even my wife. I shall still go on scolding her for my own terror, and being remorseful for it. I shall still be as unable to understand with my reason why I pray, and I shall still go on praying. But my life now—my whole life apart from anything that can happen to me—every minute of it—is no more meaningless as it was before, but has the positive meaning of goodness, which I have the power to put into it.

No man can outrun Logic or Time.

Not for the first time I find our lives are a shadow, and I am not afraid to say that people who think they have everything figured out and are masters of logic - they are responsible for the greatest folly. No human being is happy. Strike it rich and you are luckier than your neighbor - but happy, never.

No one can command over the images of your mind but an Author can and if you won't believe on me then read my book.

Not everyone can experience what other people can... That's why movies come out... films and books... and short stories and novels...

Nothing in any religious teachings goes beyond Humanism, unless you add the supernatural...Make believe is the only difference between being human and being religious.

Nothing, indeed, is more symptomatic of our modern lack of logic than our consciousness of the futility of mere material affluence in itself, and at the same time our pathetic belief that the salvation of the “poor” is to lift them into affluence!

Nothing in this world is illogical. What might seem as illogic to one, is doctrine to another. Through experiences, logic is formed and that logic influences prospective experiences until disbanded.

Nothing is necessitated whose opposite is possible.

Now, me lord, you know you oughtn’t talk like that at this hour of the morning. Yougot to pardon his lordship, sir,” he said apologetically to Jones. “His father—theduke, you know—had him schooled in logic. He can’t really help it, like.” Spoken by a most loyal valet, Tom Bryd, in defense of the inherit workings of the mind of his employer, Lord John Grey

Not too long ago thousands spent their lives as recluses to find spiritual vision in the solitude of nature. Modern man need not become a hermit to achieve this goal, for it is neither ecstasy nor world-estranged mysticism his era demands, but a balance between quantitative and qualitative reality. Modern man, with his reduced capacity for intuitive perception, is unlikely to benefit from the contemplative life of a hermit in the wilderness. But what he can do is to give undivided attention, at times, to a natural phenomenon, observing it in detail, and recalling all the scientific facts about it he may remember. Gradually, however, he must silence his thoughts and, for moments at least, forget all his personal cares and desires, until nothing remains in his soul but awe for the miracle before him. Such efforts are like journeys beyond the boundaries of narrow self-love and, although the process of intuitive awakening is laborious and slow, its rewards are noticeable from the very first. If pursued through the course of years, something will begin to stir in the human soul, a sense of kinship with the forces of life consciousness which rule the world of plants and animals, and with the powers which determine the laws of matter. While analytical intellect may well be called the most precious fruit of the Modern Age, it must not be allowed to rule supreme in matters of cognition. If science is to bring happiness and real progress to the world, it needs the warmth of man's heart just as much as the cold inquisitiveness of his brain.

Now it is such a bizarrely improbable coincidence that anything so mind-bogglingly useful could have evolved purely by chance that some thinkers have chosen to see it as the final and clinching proof of the non-existence of God. The argument goes something like this: "I refuse to prove that I exist,'" says God, "for proof denies faith, and without faith I am nothing." "But," says Man, "The Babel fish is a dead giveaway, isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED." "Oh dear," says God, "I hadn't thought of that," and promptly vanishes in a puff of logic. "Oh, that was easy," says Man, and for an encore goes on to prove that black is white and gets himself killed on the next zebra crossing.

Now, Watson," said he, "we have picked up two clues this morning. One is the bicycle with the Palmer tyre, and we see what that has led to. The other is the bicycle with the patched Dunlop. Before we start to investigate that, let us try to realize what we do know, so as to make the most of it, and to separate the essential from the accidental.

Now logic is a wonderful thing but it has, as the process of evolution discovered, certain drawbacks. Anything that thinks logically can be fooled by something else which thinks at least as logically as it does.

Objectivity begins with the realization that one is subjective.

Occam's Razor is a term plagiarized by the fact it is not easy to find its source and meaning. My attempts to find an author lead me nowhere, and I can only find unsatisfactory descriptions of how it works. Therefore, it is meaningless to me and I will use it as a placeholder to define: That which is unnecessary tends to be false. Necessity is by purpose. Therefore, purpose writes itself. Now, I have a tool.

Of course, when you shut off your brain from rational analysis, any book is dangerous. Taking literally ancient parables from thousands of years ago is much more dangerous than playing with a loaded gun. Ancient scrawls, written by different authors in different centuries with different agendas--yeah, let's get mad literal about that. The literalness problem is compounded in religion by the circular logic of not being allowed to question anything, or else you're lacking faith.

Oh, you humans may prefer empathy and mercy, but that's like intuiting the answer to an equation: you still have to go back and work the problem to be certain you were right. We can come to genuinely moral conclusions by our own paths.

One of the first unanswerable questions I asked was when I was eight years old. Some cousins of mine always said a prayer before eating: God is kind, God is good, And we thank him For our food. At that time we always heard the children in Europe were starving, therefore we should not waste any food. Two questions arose in my mind. First, what I knew about poetry was that it had to rhyme, and 'food' and 'good' didn't rhyme, so I always said 'Fud' with a silent sneer, and made it rhyme. Second: I once asked my aunt if god is good and we thank him for our Fud, why are the kids in Europe starving? I asked her if the kids in Europe were all bad. I remember her saying, 'Be thankful that you have food,' but, of course, she couldn't deal with the rest of it. I never accepted religion so I had nothing to reject as such. The history of 'Christiansanity' (my own coinage of which I am proud!) is so brutal of mind, emotions, freedom, progress, science, and all that I hold precious, that by any standards of justice its leaders in almost any given period would be incarcerated for life, or worse!

One chooses logical argument only when one has no other means. One knows that one arouses mistrust with it, that it is not very persuasive. Nothing is easier to nullify than a logical argument: the tedium of long speeches proves this. It is a kind of self-defense for those who no longer have other weapons. Unless one has to insist on what is already one's right, there is no use for it. The Jews were argumentative for that reason; Reynard the Fox also — and Socrates too?

One can only see what one observes, one observes only things which are already in the mind.

One needs to be Supernatural or Insane to defy Logic.

One of the difficulties in raising public concern over the very severe threats of global warming is that 40 percent of the US population does not see why it is a problem, since Christ is returning in a few decades. About the same percentage believe that the world was created a few thousand years ago. If science conflicts with the Bible, so much the worse for science. It would be hard to find an analogue in other societies.

[One way] researchers sometimes evaluate people's judgments is to compare those judgments with those of more mature or experienced individuals. This method has its limitations too, because mature or experienced individuals are sometimes so set in their ways that they can't properly evaluate new or unique conditions or adopt new approaches to solving problems.

People will hold an opinion because they want to keep the company of others who share the opinion, or because they think it is the respectable opinion, or because they have publicly expressed the opinion in the past and would be embarrassed by a “U-turn,” or because the world would suit them better if the opinion were true, or . . . Perhaps it is better to get on with your family and friends, to avoid embarrassment, or to comfort yourself with fantasies than to believe the truth. But those who approach matters in this way should give up any pretensions to intellectual seriousness. They are not genuinely interested in reality.

On one side of his brain, logic was standing on a chair, waving its arms to get his attention. On the other side, lust and yearning rubbed their hands together in unholy anticipation.

Origin of the Logical. Where has logic originated in men’s heads? Undoubtedly out of the illogical, the domain of which must originally have been immense. But numberless beings who reasoned otherwise than we do at present, perished; albeit that they may have come nearer to truth than we! Whoever, for example, could not discern the "like" often enough with regard to food, and with regard to animals dangerous to him, whoever, therefore, deduced too slowly, or was too circumspect in his deductions, had smaller probability of survival than he who in all similar cases immediately divined the equality. The preponderating inclination, however, to deal with the similar as the equal - an illogical inclination, for there is no thing equal in itself - first created the whole basis of logic. It was just so (in order that the conception of substance should originate, this being indispensable to logic, although in the strictest sense nothing actual corresponds to it) that for a long period the changing process in things had to be overlooked, and remain unperceived; the beings not seeing correctly had an advantage over those who saw everything "in flux." In itself every high degree of circumspection in conclusions, every sceptical inclination, is a great danger to life. No living being might have been preserved unless the contrary inclination - to affirm rather than suspend judgment, to mistake and fabricate rather than wait, to assent rather than deny, to decide rather than be in the right - had been cultivated with extraordinary assiduity. - The course of logical thought and reasoning in our modern brain corresponds to a process and struggle of impulses, which singly and in themselves are all very illogical and unjust; we experience usually only the result of the struggle, so rapidly and secretly does this primitive mechanism now operate in us.
