Abstract: This paper delves into Wittgenstein’s Tractatus to unearth the two distinct probability notions within it: logical probability and epistemic probability. Our study yields three pivotal conclusions. Firstly, the concept of logical probability is susceptible to an axiomatic framework, but its practical utility remains restricted. Secondly, the interpretations of 5.152 pertaining to probability and independence present certain challenges for some readers. Finally, epistemic probability emerges as a logical deduction derived from hypothetically assumed natural laws, impervious to empirical validation or refutation by observed frequencies.
