When you look into the history of the state of knowledge in fields of physics, chemistry, or biology, it seems like more often than not, one of the earliest sources that is being discussed is Aristotle. Who was the gold standard for science for centuries, but also happened to be laughably wrong about apparently everything because he never bothered to go looking for evidence. Guy was just good at writing down things he assumed and making other people cite him as a source.

Did he actually get anything right? Is there any reason to still consider him an important scholar who made relevant contributions to human knowledge?

Every time I come across one of his bogus claims, I am thinking more and more that he probably might have been the single most responsible person for keeping science back.

Did he have any positive contribution?
