Aristotle wrote very widely. From the first description of octopus mating behavior to the first stab at formal logic ever, there are probably a lot of topics where he was wrong, but also a lot of other ones where he was right, where debate is still open or where his position was refined.

That his scripture was treated as canon by the christian church and not subjected to further scientific inquiry is one of the foundational stories of the modern science. That story is certainly not wrong though it lacks nuance. It is also where Aristotle’s bad rep is mostly from.

Aristotle‘s position on many topics is simply the first one uttered as far as we know. It is interesting because it is the start of a conversation, not because it is right or wrong.

He was the first to develop formal logic which is a foundation of computer science.

You may be wrong a thousand times but right once... Benefit of doubt I guess

Why do you think Aristotle was wrong about drama/poetics?
