The strength of a theory is not what it allows, but what it prohibits; if you can invent an equally persuasive explanation for any outcome, you have zero knowledge.
[...] intelligent people only have a certain amount of time (measured in subjective time spent thinking about religion) to become atheists. After a certain point, if you're smart, have spent time thinking about and defending your religion, and still haven't escaped the grip of Dark Side Epistemology, the inside of your mind ends up as an Escher painting.
Interpretation
What this quote means
Intelligent individuals have limited time to reconsider their beliefs, and clinging to unfounded ideologies can lead to a confused and paradoxical mindset.
In this quote, Eliezer Yudkowsky discusses the intellectual journey individuals undergo regarding their beliefs, particularly religion. He suggests that those who are intelligent and spend significant time contemplating their faith should eventually reach a point of clarity, but if they remain entrenched in dogma, their rational thinking may become convoluted and contradictory, akin to the impossible constructions seen in Escher's art. This serves as a cautionary note against the dangers of adhering to beliefs without critical examination.

The obvious choice isn't always the best choice, but sometimes, by golly, it is. I don't stop looking as soon I find an obvious answer, but if I go on looking, and the obvious-seeming answer still seems obvious, I don't feel guilty about keeping it.
When something is universal enough in our everyday lives, we take it for granted to the point of forgetting it exists.

I feel, am mad as any writer must in one way be; why not make it real? I am too close to the bourgeois society of suburbia: too close to people I know I must sever my self from them, or be a part of their world: this half and half compromise is intolerable.
