"The knowledge of anything, since all things have causes, is not acquired or complete unless it is known by its causes"
About this Quote
The subtext is quietly ambitious. Avicenna is insisting that reality is intelligible and structured, that the human mind can climb from effects to causes and arrive at something stable. This is Aristotelian method filtered through an Islamic Golden Age confidence in reason: medicine, astronomy, metaphysics all become legitimate because they can be organized as causal explanations rather than as mere craft or inherited lore.
The phrase “acquired or complete” matters. It suggests knowledge has a lifecycle: you can start with experience, but completion requires explanation. It’s an epistemology that privileges demonstration over testimony. It also smuggles in a moral hierarchy of minds: the better intellect is the one that doesn’t just notice patterns but can account for them. Read now, it sounds like a prototype of the modern scientific instinct - yet broader, because Avicenna’s causal ladder ultimately points past physics to metaphysics, toward first principles. The rhetoric works because it’s spare and uncompromising: no cause, no claim to knowing.
