This shift from consequentialist reasoning to values-driven action is predictable, and it is how most foreign policy disasters begin. "Under certain circu https://umerazad.com/notes/the-modern-state-is-not-a-neutral-tool.html Fri, 11 Sep 2020 00:00:00 +0000 Modern Islamist movements treat the nation-state as a neutral instrument that can be harnessed for Islamic purposes. Hallaq argues this is as naive as thinking Aristotelian logic was a neutral technique, until Muslim intellectuals themselves demonstrated it was saturated with particular metaphysical https://umerazad.com/notes/the-west-misreads-islam-through-its-own-categories.html Fri, 11 Sep 2020 00:00:00 +0000 Orientalism is not an aberration in Western intellectual history; it is a logical product of a worldview that strips the world of spiritual essence and reduces everything, including human beings, to objects of study. "Why did Europe birth Orientalism and equate difference with weakness? The premode https://umerazad.com/notes/singapore-was-engineered-not-inevitable.html Sun, 06 Sep 2020 00:00:00 +0000 Singapore's transformation from a Third World port to a First World city-state was not the natural result of "enlightened authoritarianism" applied generically. It was the product of specific political maneuvers, ruthless pragmatism, and conditions that cannot be exported.

If you know less about the reliability of the measuring instrument than about the thing being measured, the measurement tells you more about the instrument than about the reality.

No — they sidestep the hard problems of resource sharing and only succeed by avoiding the issues that make OS design genuinely difficult."

Its longevity comes from addressing the invariant truths of engineering: that design is about tradeoffs, interfaces outlive implementations, and simplicity is the hardest th https://umerazad.com/notes/hub-notes.html The notes below have the highest connection density in this vault, measured by total wikilinks (both incoming and outgoing).
