This review of Galen's 'On the Natural Faculties' challenges common misconceptions about the ancient physician, portraying him as more empirical and scientifically-minded than typically believed.

Scott Alexander uses three fictional stories to illustrate principles of non-empirical scientific reasoning, ultimately applying them to support the many-worlds interpretation of quantum mechanics.

Scott Alexander argues that non-empirical reasoning, based on principles like simplicity and elegance, is a necessary and legitimate part of scientific practice, even for evaluating seemingly untestable theories.

Scott Alexander argues against the fear of angering simulators by testing if we're in a simulation, stating that competent simulators would prevent discovery or expect such tests as part of civilizational development.

Scott Alexander presents highlights from reader comments on his review of Kuhn's 'The Structure of Scientific Revolutions', offering various perspectives and clarifications on Kuhn's ideas about scientific progress.

Scott Alexander presents a 'Grand Unified Chart' showing how different domains of knowledge share a similar structure in interpreting the world, arguing this is due to basic brain algorithms and effective epistemology.

Scott reviews Kuhn's 'Structure of Scientific Revolutions', finding its thesis on paradigm shifts in science intriguing but frustratingly vague, especially beyond physics.

Scott Alexander refutes a blog post criticizing rationalism, arguing it misunderstands the movement and its core values of empiricism, scholarship, and humility.

Scott Alexander criticizes a Guardian article's flawed reasoning in claiming 'Limits to Growth' accurately predicts economic collapse, comparing it to the philosophical 'grue-bleen induction problem'.

Scott Alexander reviews 'Quantum Computing Since Democritus' by Scott Aaronson, sharing insights gained despite the book's complexity and his own mathematical limitations.

Scott Alexander defends logical positivism, arguing that despite its flaws, it points to useful ideas about dividing meaningful statements into scientific and logical categories.
