"Now it is established in the sciences that no knowledge is acquired save through the study of its causes and beginnings, if it has had causes and beginnings; nor completed except by knowledge of its accidents and accompanying essentials"
About this Quote
The intent is surgical. “Causes and beginnings” signals the Aristotelian backbone of his project: knowledge isn’t a pile of observations, it’s an explanation structured by why-questions. A thing becomes intelligible when you can place it inside a causal story. That’s why this isn’t just about origins, but about intelligibility as such. If the phenomenon has no “beginnings” (think eternal truths or necessary beings), then you don’t force a fake genealogy; you shift the inquiry to what makes it necessary.
The subtext is also a critique of mere description. You can catalog symptoms, but medicine only hardens into science when it links symptoms to etiology. You can list properties, but philosophy only “completes” its account when it distinguishes what’s essential from what’s accidental - what must be there for the thing to be what it is, versus what merely happens to tag along.
Context matters: Avicenna is working at the seam between metaphysics and empiricism, trying to make rigorous knowledge possible without collapsing into either mysticism or raw sense-data. The sentence is a blueprint for disciplined explanation - and a warning that knowledge without structure is just well-organized ignorance.
