OK! So what is constructive skeptical philosophy?

My understanding of "skeptical philosophy" would be, e.g., Hume. Philosophy that emphasizes empiricism and is distant from "metaphysical speculation."

It might be related to the current "skeptical movement" which discounts or investigates supernatural claims and experiences. And that might explain "constructive," if the goal is to engage and not offend.

So, what is this group aiming to discuss?
