Critical Thinking Quotes

“Doubt as sin. — Christianity has done its utmost to close the circle and declared even doubt to be sin. One is supposed to be cast into belief without reason, by a miracle, and from then on to swim in it as in the brightest and least ambiguous of elements: even a glance towards land, even the thought that one perhaps exists for something else as well as swimming, even the slightest impulse of our amphibious nature — is sin! And notice that all this means that the foundation of belief and all reflection on its origin is likewise excluded as sinful. What is wanted are blindness and intoxication and an eternal song over the waves in which reason has drowned.”
― Friedrich Nietzsche, Daybreak: Thoughts on the Prejudices of Morality

The colors are like no other, they swim and leap, they trickle and embellish! And yet you choose to fixate your eyes on the small fly which has landed on it! Why do you do such a thing?”
― C. JoyBell C.

“Forget the politicians. The politicians are put there to give you the idea you have freedom of choice. You don't. You have no choice. You have owners. They own you. They own everything. They own all the important land, they own and control the corporations that've long since bought and paid for, the senate, the congress, the state houses, the city halls, they got the judges in their back pocket, and they own all the big media companies so they control just about all of the news and the information you get to hear. They got you by the balls. They spend billions of dollars every year lobbying to get what they want. Well, we know what they want. They want more for themselves and less for everybody else. But I'll tell you what they don't want. They don't want a population of citizens capable of critical thinking. They don't want well informed, well educated people capable of critical thinking. They're not interested in that. That doesn't help them.”
― George Carlin

― Brian Cox

“We are all in favor of emotional intelligence. Intelligence can take emotion as a privileged counseling partner. However, it does not allow the emotion to take possession of us, besiege our mind, and subjugate our thinking. The emotion must regulate our thoughts, not manipulate nor substitute them. Our perception is only a biased picture of reality, and emotions are individual or provisional. Therefore, critical thinking and emotional thinking must go hand in hand. ("No monsters hide at this point" )”
― Erik Pevernagie

[With analogy] we are doing this because it’s like something else that was done, or it is like what other people are doing. [With first principles] you boil things down to the most fundamental truths…and then reason up from there.”
― Elon Musk

“I had a long talk with my dear Fat Mary that night, because I had many questions. Could someone actually be beaten to death by such a nun? Did Mother Rufina, the new Superior, know that Sister Clotilda was so cruel? Who let her work with children? Could nuns go to hell?
Fat Mary told me she didn’t know the answers to my questions, but she reminded me that it was her role to take my worries and burdens and keep them for me until a time when I could understand them.”
― Maria Nhambu, Africa's Child

“You do not win by struggling to the top of a caste system, you win by refusing to be trapped within one at all.”
― Naomi Wolf, The Beauty Myth

“Let us not become victims of a crippling reasoning pattern. If we want to improve our decision-making and critical thinking, we must recognize our mental biases and be willing to overcome them. Let us avoid creating arguments to confirm pre-existing beliefs at all costs and invest in a ‘sunk cost fallacy.’ Better alight from a car out of control than drive it off the cliff. (“The infinite Wisdom of Meditation“)”
― Erik Pevernagie
