A Lesson in the Practicality of Philosophy I Learned Today

[Neo-Scholastic]

Seems circular. Can you prove a proposition that science is the only reliable method for confirming objective knowledge by using scientific methods?

...By objective knowledge I take you to mean conception of the real objects that exist in perception, and by scientific method, the careful examination of those objects and their relation to other objects as well as the subject. So, considering our alternatives, yes.

And with that statement you appear to be retreating from the requirement of predictive value. Nothing in the description you just presented excludes metaphysical inferences from and about the nature of sensible bodies.
