Having read a few philosophers, I don't really see any fundamental difference between Feser's approach and those of other philosophers. All philosophers have their positions and try to construct arguments to support those constructions. Feser's positions are traditional Roman Catholic positions, but your average atheist philosopher (such as Graham Oppy or J. L. Mackie) is doing the same basic thing.

I feel like your expectations for how philosophers ought to behave aren't based on any significant familiarity with the work of actual philosophers, just your suppositions about how philosophy ought to be done.

Good point: perhaps I have an unrealistic, dumb, ill-educated or otherwise malformed ideal/view that philosophers should somehow be constantly challenging their own ideas, using their writing/discourse as an instrument to help them reach better conclusions through statement/contradiction (something like constructing an academic essay using thesis/antithesis/synthesis I guess?) and disputing them internally… Actually, as you suggest, the ‘correct’ approach to philosophy, or at least the only realistically possible approach, is to repeatedly state prior beliefs in the most persuasive way possible and then presumably to defend your a priori views from any challenges by others - only ‘testing’ those ideas in reaction by engaging in external debate rather than an internal one… I wonder though, doesn’t the outcome/process of that debate have to register internally somehow, for one side at least, for it to have any point? …for an evolution of the thinkers involved’s ideas to take place, is it not necessary for one/both sides in a debate to have at least a somewhat open mind, even as they strongly debate their particular ‘side’? …to allow one side to change its mind when the arguments put forward by the opposition are significantly strong - otherwise the debate would inevitably become stale, never-changing and circular? If one side is fixed in its beliefs, why would the other side bother debating them at all? If they were interested in adopting those ideas they should merely ‘receive’ them, rather than engage in an inevitably fruitless debate? I suppose if you have an unshakable belief that there exists an eternal and ever-present truth that you are inalterably sure of, and others who don’t agree with you are simply less enlightened, then you may feel that you should never have cause to change your mind - why should you, as you are already privy to the ultimate truth? Your task then, if you are communicative/evangelical/missionary in some way at least, is only to expound that truth to others? Your writing becomes a vehicle to promote your ‘truth’ - truth informed by mystically or intuitively received wisdom, never conjecture… Your debate/writing etc. is not a way to clarify your own ideas, but rather to show others the folly of contrary thoughts?
