Was logic invented or discovered?

[Neo-Scholastic]

Logic is a discipline derived from the belief in an orderly reality capable of being understood. The idea of a universe that is inherently orderly is a necessary axiom for rational thought.

Why do you think belief preceded observation? Much of logic is easily demonstrable.

Maybe you misunderstood or I was not sufficiently clear. Logic serves us at a very high level of cognition. Our application of that mental disciple gives meaning to observation. Observations, if taken to mean pattern recognition, sits down a notch, then perceptions, and down to sensation. Application of logic requires us to presuppose that each of these lower levels falls within a reality governed by intelligible laws.
