Is logic based on uncertainty the fundamental logic?

Most formal logics are based on certainty, but certainty is only one probability among others, so a logic based on uncertainty and probability should be considered as the fundamental logic from which all others derive ?

(Perhaps) another way of presenting the question: deduction is a form of induction, so inductive logic must be the fundamental logic?

• I really can't follow what you're asking. What makes you say that deduction is a form of induction? Deduction is inherently certain (granting true premises), induction is inherently uncertain. I would say it's more like induction is based on deduction, with an additional "inductive step" thrown in, which is what generates the uncertainty. Deduction, is definitely the most "fundamental logic", in my opinion, although both are very useful even though induction doesn't provide absolute certainty. – monster319 Jan 15 '17 at 21:19
• Certainty is only a mood. – Mr. Kennedy Jan 16 '17 at 0:00
• Maybe take a look at fuzzy logic, e.g., en.wikipedia.org/wiki/Fuzzy_logic – John Forkosh Jan 16 '17 at 2:34
