Why did Hobbes consider geometry a model for genuine knowledge?

Thomas Hobbes viewed geometry as a model for genuine knowledge primarily due to its reliance on a rigorous, deductive method. After encountering Euclid’s Elements, Hobbes became captivated by the power of demonstrating theorems through logical progression.12

For Hobbes, philosophy was essentially a form of reasoning or "calculating" the causes and effects of phenomena. He distinguished between two types of reasoning:23
* Analytical: Reasoning from effects back to causes.23
* Synthetic: Reasoning from causes to effects.23

Hobbes strongly favored the synthetic approach, which mirrors the structure of geometric proofs. Because he believed the physical world consists entirely of matter in motion, he sought to apply this same systematic, deductive certainty to all areas of inquiry, including physics, psychology, and civil philosophy. By treating knowledge as a chain of logical deductions derived from fundamental principles, he aimed to achieve the same level of clarity and irrefutable truth found in mathematics.2341
