Quotes About Reason

Let us then suppose the mind to be, as we say, white paper void of all characters, without any ideas. How comes it to be furnished? Whence comes it by that vast store which the busy and boundless fancy of man has painted on it with an almost endless variety? Whence has it all the materials of reason and knowledge? To this I answer, in one word, from EXPERIENCE.

If you extol reason, then what matters is the integrity of the thoughts, not the personalities of the thinkers. And if you're committed to progress, you can't very well claim to have it all figured out. It takes nothing away from the Enlightenment thinkers to identify some critical ideas about the human condition and the nature of progress that we know and they didn't. Those ideas, I suggest, are entropy, evolution, and information.

Remember your math: an anecdote is not a trend. Remember your history: the fact that something is bad today doesn't mean it was better in the past. Remember your philosophy: one cannot reason that there's no such thing as reason, or that something is true or good because God said it is. And remember your psychology: much of what we know isn't so, especially when our comrades know it too.

Fashionable academic movements like postmodernism and critical theory (not to be confused with critical thinking) hold that reason, truth, and objectivity are social constructions that justify the privilege of dominant groups.

Can reason lead us in directions that are good or decent or moral? After all, you pointed out that reason is just a means to an end, and the end depends on the reasoner's passions. Reason can lay out a road map to peace and harmony if the reasoner wants peace and harmony, but it can also lay out a road map to conflict and strife if the reasoner delights in conflict and strife. Can reason force the reasoner to want less cruelty and waste?

To make decisions "rationally," by some set of rules, means to base the decisions on some grounds of truth:

The beauty of reason is that it can always be applied to understand failures of reason.

How, then, can we understand this thing called rationality which would appear to be our birthright yet is so frequently and flagrantly flouted?

The decline of violence may owe something to an expansion of empathy, but it also owes much to harder-boiled faculties like prudence, reason, fairness, self-control, norms and taboos, and conceptions of human rights. This

Submitting all of one's beliefs to the trials of reason and evidence is an unnatural skill, like literacy and numeracy, and must be instilled and cultivated.

reason, by itself, is just a means of getting from one true proposition to the next and does not care about the value of those propositions.

Enlightenment's motto, he proclaimed, is "Dare to understand!" and its foundational demand is freedom of thought and speech.

And the story belongs not to any tribe but to all of humanity—to any sentient creature with the power of reason and the urge to persist in its being. For it requires only the convictions that life is better than death, health is better than sickness, abundance is better than want, freedom is better than coercion, happiness is better than suffering, and knowledge is better than superstition and ignorance.

Si uno ensalza la razón, entonces lo que importa es la integridad de los pensamientos, no las personalidades de los pensadores.

Those who are governed by reason desire nothing for themselves which they do not also desire for the rest of humankind.

Far from sprouting from the grass roots or channeling the anger of know-nothings, the disdain for reason, science, humanism, and progress has a long pedigree in elite intellectual and artistic culture.

Rather than trying to shape human nature, the Enlightenment hope for progress was concentrated on human institutions. Human-made systems like governments, laws, schools, markets, and international bodies are a natural target for the application of reason to human betterment.

The major enemy of reason in the public sphere today—which is not ignorance, innumeracy, or cognitive biases, but politicization—appears to be on an upswing.

Si algo tenían en común los pensadores ilustrados era su insistencia en que apliquemos enérgicamente el estándar de la razón a la comprensión de nuestro mundo y no recurramos a generadores de engaño como la fe, el dogma, la revelación, la autoridad, el carisma, el misticismo, la adivinación, las visiones, las corazonadas o el análisis hermenéutico de los textos sagrados.

The alternative, then, to the religious theory of the source of values is that evolution endowed us with a moral sense, and we have expanded its circle of application over the course of history through reason (grasping the logical interchangeability of our interests and others'), knowledge (learning of the advantages of cooperation over the long term), and sympathy (having experiences that allow us to feel other people's pain).

our own susceptibility to illusions and fallacies, tell us that men and women are fallible. One therefore ought to seek good reasons for believing something. Faith, revelation, tradition, dogma, authority, the ecstatic glow of subjective certainty—all are recipes for error, and should be dismissed as sources of knowledge.

there's nothing common about common sense.

Remember your math: an anecdote is not a trend. Remember your history: the fact that something is bad today doesn't mean it was better in the past. Remember your philosophy: one cannot reason that there's no such thing as reason, or that something is true or good because God said it is.
