tension between necessity and contingency

Necessity and contingency are concepts in philosophy and logic that relate to how things happen. Necessity means something must happen—it’s inevitable and unchangeable, like mathematical truths. Contingency means something could go either way; it’s dependent on circumstances and isn’t predetermined, like whether it will rain tomorrow. The tension arises because some things seem necessary (laws of nature), while others are contingent (specific events). Understanding this helps us grasp what is fixed and what is variable in the world, shaping how we think about fate, free will, and the nature of reality.
