I'd like to espouse a (perhaps somewhat modernised) Humean scepticism.
Scepticism may be thought of like the heavy pruning of garden plants. Apparently a vicious attack, but one which lays a foundation for healthy future growth. Every false belief is an impediment to realising the truer, and a dose of scepticism clears the way to enlightenment.
Humean scepticism is of particular relevance here because it can be read as a more precise drawing of the line between necessary and contingent propositions.
