Was Buddha a Contextualist

I heard the following quote today

Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense. – Buddha

And here is Cem Kaner’s most recent definition of what Context-driven testing is.

Context-driven testers choose their testing objectives, techniques, and deliverables (including test documentation) by looking first to the details of the specific situation, including the desires of the stakeholders who commissioned the testing. The essence of context-driven testing is project-appropriate application of skill and judgment. The Context-Driven School of testing places this approach to testing within a humanistic social and ethical framework.

Both these quotes seem to shoot down both the notion of ‘Best Practices’ and ‘Cult of the Expert’. Instead they say that a tester should use their brain and their own judgment in each situation before doing an action.

I don’t know the religious views of most people involved in the content school, but I know a couple and can safely say that all contextualists are not buddhist. If we take that as a truth, then how about the opposite? Was Buddha a contextualist?
