Logic Quotes

“Pragmatism, by its very name, poses above all as a 'pholosophy of action'; its more or less avowed assumption is that man only has needs of a practical order, material ones and, together with these, sentimental ones. It means, then, the doing away with intellectuality; but, if this is so, why go on wanting to evolve theories? That is rather hard to understand; and if pragmatism, like skepticism, which it only differs from with regard to action, wished to conform to its own standards, it would have to limit itself to a mere mental attitude, which it cannot even seek to justify logically without giving itself the lie; but there is no doubt that it is very difficult to keep strictly within such bounds.”

“Logic is present in both the master and the fool. Logic to the fool is: "If I attack the neighbor, I get his food and his house and his wife." Logic to the master is: "If I build 8,000 houses, it will solve the problem of all the fools attacking their neighbors and stealing their wives!" The moral of the story is: be careful what you make sense of. Something will always make total sense, to the person making sense of it.”

“A poem for the rulers of nations. "Heavy lies the head that bears the crown, A weight of power, from dusk to dawn. In regal halls, with scepter and throne, The ruler's heart carries burdens unknown. Heavy lies the head, but it bears the weight, Of destiny's hand, of a kingdom's fate. Through trials and triumphs, they must lead, For the crown they wear is the nation's need. Served with platters of rumours and hate, Still they feed our nations from a selfless plate. Endless gossip and selfish press, Yet they take the punch with no regret. With grace and strength, they rise above, Their duty to cherish, their people to love. In the realm they govern, their hearts resound, For heavy lies the head that wears the crown.”

“Leibniz wanted to combine physics, mathematics, logic, and philosophy, and he would no doubt have loved this joke: An engineer, a mathematician, a logician, and a philosopher were traveling through Scotland when they saw a black sheep through the window of the train. "Aha", says the engineer, "I see that Scottish sheep are black." "Hmm", says the mathematician, "You mean that some Scottish sheep are black." "No", says the logician, "All we know is that there is at least one black sheep in Scotland." "And even", the philosopher continued, "The only thing we can be really sure of is that the side facing us is black.”

“Landscape Mathematicians, Matemáticos Paisajistas, are mathematical thinkers, designers, philosophers, scientists, and inventors, and can easily recognize and understand the beauty and logic of this world of numbers. Nature illustrates the language of mathematics; and Landscape Mathematicians translate this beauty and logic. We are the common denominators in all fields. Mathematics is our first language! By translating the mathematical systems we see in colors, shapes, and numbers, we reveal the logic of this beautiful world. Landscape Mathematicians see a world of numerical solutions. We see a world of Landscape Mathematics!”

“No matter what, keep moving forward. The hardships that you experience in life make you stronger. Most importantly, self-respect is key. In order to have a positive ending, you do not need to start with a positive beginning. The quality of your mind is what determines your future.”

“Most importantly, I want people to know that the impossible is attainable and that if one person believes in you, then you are already making a difference. Through experience I have learned that there are two different sides in life: the good and the cruel. In order to value one side, you must experience both of them. You will come across people who will recognize your potential, as well as others who will try to lower your confidence, belittle you, or even try to discredit your reputation. For example, this can be seen in situations where someone may be biased against you because of what you do, the way you think, or who you are as a person. Keep moving forward. The hardships that you experience in life make you stronger.”

“Great mathematicians are born with a brain fundamentally different from ours. We may as well be clear about the first one: no, mathematicians don’t think logically. It is in fact utterly impossible to think logically. Logic doesn’t help at all with thinking. We shall see later on what it is used for.”

“In a traditional civilization it is almost inconceivable that a man should claim an idea as his own; [...] If an idea is true, it belongs equally to all who are capable of understanding it; if it is false, there is no credit in having invented it. A true idea cannot be 'new', for truth is not a product of the human mind; it exists independently of us, and all we have to do is to take cognizance of it; outside this knowledge there can be nothing but error: but do the moderns on the whole care much about truth, or do they even know what it is? Here again words have lost their real meaning, inasmuch as some people-for instance contemporary pragmatists-go so far as to misappropriate the word 'truth' for what is simply practical utility, that is to say for something that is quite foreign to the intellectual order. The logical outcome of the modern deviation is precisely the negation of truth, as well as of the intelligence of which truth is the object.”

“If adding two numbers produced a random result each time, we could never rely on math. Fortunately there are definite answers with no variation. Similarly, there is nothing random about the study of science. If each iteration of an experiment yielded a different result from the same variables, we would not be able to conclude anything with certainty. The scientific method is not compatible with randomness. If the universe were truly random, the study of science itself would not be possible. The laws of nature stand in direct opposition to the notion that all is born of chance.”

“While I was at University, and afterward, I behaved in what seemed to me to be a logical manner. But now I realize that what I did was do things irrationally, and then after I would arrange the events in my mind so they seemed to follow some sort of reasonable path. That is not logic -- it is wishful thinking, and involves rewriting one's own history as one goes along. Life is not logical -- it just goes along happening, and the best anyone can do is try to deal with the present as well as they can.”

“Contrary to the standard caricature of philosophers as inveterate skeptics who have no truck with religion, among philosophers the view that the existence of God can be rationally demonstrated “enjoyed wide currency, if not hegemony . . . from classical antiquity until well after the dawn of modernity” (to quote the philosopher David Conway, writing in a book that had a major influence on Flew’s conversion to philosophical theism); and the suggestion that human reason can be accounted for in purely materialistic terms has, historically speaking, been regarded by most philosophers as a logical absurdity, a demonstrable falsehood.”

“The possibility of the existence of such a thing as "science" rests on a variety of presuppositions that neither can themselves be subjected to a "scientific" examination, nor do they provide any rational basis for giving said "science" the authority of the last word not only on general questions of human existence, but even in the specialized field of each particular scientific area. Just to give an basic example, without the words "yes" and "no", logical reasoning is not possible. No science can tell us what they mean. All formal logic is based on these two words, and formal logic itself cannot define them.”

“Well, Humpty Dumpty is one of the keenest arguers I know... he almost had me convinced that I had no valid reason to be sure that I was awake... It took me about three hours, but I finally convinced him that I must be awake, and so he conceded that I had won the argument. And then--." The King did not finish his sentence and stood lost in thought. "And then what?" asked Alice. "And then I woke up!" said the King, a bit sheepishly.”

“The materialistic atheist can’t have laws of logic. He believes that everything that exists is material—part of the physical world. But laws of logic are not physical. You can’t stub your toe on a law of logic. Laws of logic cannot exist in the atheist’s world, yet he uses them to try to reason. This is inconsistent. [...] The atheist’s view cannot be rational because he uses things (laws of logic) that cannot exist according to his profession. The debate over the existence of God is a bit like a debate over the existence of air.3 Can you imagine someone arguing that air doesn’t actually exist? He would offer seemingly excellent “proofs” against the existence of air, while simultaneously breathing air and expecting that we can hear his words as the sound is transmitted through the air. In order for us to hear and understand his claim, it would have to be wrong. Likewise, the atheist, in arguing that God does not exist must use laws of logic that only make sense if God does exist. In order for his argument to make sense, it would have to be wrong.”

“There is a time and place to use good judgment. Using common sense is wise. Having discernment is imperative. No doubt about it, our analytical skills can help us to identify and define problems. Our logical minds can assist us to find realistic solutions. Finding balance with our logic and our intuition is essential.”
