I'm a huge fan of Aristotle. He's more or less the founding father of all western intellectual tradition. But he believed things like continuous force is necessary to keep an object in motion and object released from a rotational anchor would move perpendicular to the rotation's tangent. Beware any non-experimental version of science that relies entirely upon deducing what seems obvious to you from first principles. Even with strong math behind it, you get things like zero point energy density computed from quantum mechanics being off by triple-digit orders of magnitude from the true observed value, often called the worst prediction in the history of physics. Only reality, not your mind, holds truth. There is no "personal" truth, aside from true statements regarding your own feelings, beliefs, and other indicators of purely subjective internal state.
