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.

When something is universal enough in our everyday lives, we take it for granted to the point of forgetting it exists.

It's important for people of colour to have the opportunities to play characters that are as nuanced - as three-dimensional, as human - as the characters who we traditionally see getting to play the protagonist.
