But perhaps the problem is not so bad if we reject Platonism. I tend to think that philosophical (as opposed to material) facts are not really things that exist out in the world. Though objective enough, their ontological status is better seen as that of a rational construction. According to this view -- call it "
So what does all this mean for the reliability of our intuitions? Well, if they no longer have to answer to an independently existing realm of facts, perhaps they're not in such bad condition as we thought. Note that I'm not denying that there is an objective truth of the matter for many philosophical questions, so that our intuitions may in fact lead us astray (if ideal rational reflection would cause us to revise them, for example). Our intuitions must answer to this rational construction; the point is that the construction may not be wholly independent of them in the first place.
In short: the views we hold now, which are prima facie coherent and plausible, are reasonable - if fallible - guides to what we would find coherent and plausible on ideal rational reflection (which, for philosophical questions, is simply to say what is true). Intuitions have justificatory force because they're already on the road to constituting truths. Sure, obstacles might arise on further reflection that prevent the initial beliefs from being true after all. But otherwise, they're home free.
