I have always viewed these types of arguments as, "Too hard for me to solve, so I guess they can't be objective or real. — Philosophim
Exactly.
In the strictest sense, I agree that there might not be anything real or moral at all. But all we could do in that case is one of two things. We could either baselessly assume that there is nothing real or moral at all, and stop there, simply giving up any hope of ever finding out if we were wrong in that baseless assumption. Or else, instead, we could baselessly assume that there is something real and something moral – as there certainly inevitably seems to be, since even if you deny their universality some things will still look true or false to you and feel good or bad to you – and then proceed with the long hard work of figuring out what seems most likely to be real and moral, by attending closely and thoroughly to those seemings, those experiences.

Thinking you need a starting point is what makes it seem impossible.
Any reason put forth in support of some opinion is itself another opinion, for which the justificationist must then, if consistent with this principle, demand yet another reason. But that in turn will be some other opinion, for which the same demand for justification must be made. And so forth ad infinitum. This can only lead to one of three outcomes:
The most typical one is foundationalism. This abandons the principle of justification at some point by declaring some step of the regress of demands for justification to be self-evident, beyond question, without need of further support. That is transparently tantamount to dogmatism. Nevertheless, as I will soon explain, I have sympathy for the need to hold some opinions without them being rigorously supported from the ground up. I simply reject holding them to thus be unquestionable.
Another possible outcome is coherentism. This appeals at some point to an earlier step in that regress as support for a later one, establishing a circular chain of reasons that together can then support other reasons. I am sympathetic to the coherency criterion employed here, as surely all of one's opinions must be consistent with each other, and finding inconsistencies is a good reason to rule out some opinions.
But while that is a necessary feature, I think it is not a sufficient one: mere consistency is not enough to justify opinions in the sense demanded by justificationism, without again falling to dogmatism. For as that whole circular chain of reasons is then collectively unsupported and held as needing no further support besides itself, it is then, as a whole, tantamount to one big foundational, and therefore dogmatist, opinion.
The last possible outcome, and the most honest application of justificationism (in that it never breaks from the demand for reasons, to hide instead in dogmatism), is infinitism. This accepts the infinite regress of demands for justification, leaving the initial opinion, any and every initial opinion looking to be supported, forever insufficiently supported. That leaves one unwarranted in holding any opinion, and so is transparently tantamount to relativism.
Self-avowed infinitists do at least nominally hold that knowledge is still possible, and therefore conclude that it must somehow be possible to have an infinite chain of justification, even while acknowledging that it would be impossible for anyone to ever complete one in practice. While I am again sympathetic to this unending search for deeper and deeper principles to underlie our opinions, as I will soon elaborate, this infinitist position seems to me simply incoherent when framed as a form of justificationism: if you cannot ever complete the chain of justification, and you must have justification to have knowledge, then you cannot ever have knowledge.
Most theories of knowledge are either foundationalist or coherentist, and most of those who reject both of those conclude that therefore knowledge is impossible, seeing infinitism to be as incoherent as I do. But a few philosophers, including Immanuel Kant and Karl Popper, have instead rejected the justificationist principle tacitly underlying all of those positions, and instead say, as do I, that
it is not necessary to reject every opinion until you can find reasons to justify it; it is only necessary to reject an opinion if you find reasons to reject it, and it is acceptable to hold any opinion, for no reason at all, until such reasons to reject it are found.
Like with coherentism, contradictions between different opinions are good reasons to reject some or all of them; and like with infinitism, this process of whittling away incorrect opinions is unending. But because both coherentism and infinitism tacitly accept the justificationist principle, neither of them quite adequately escapes the dilemma of either following it into relativism, or else abandoning it for dogmatism.
When considering reasons to intend something rather than reasons to believe something, this anti-justificationism seems largely uncontroversial. Most people will accept that it is acceptable to do something simply because you want to do it, for no particular reason, so long as there is not a good reason not to do it. We don't demand that everybody stop doing anything at all until they can show that what they want to do is justified by the need to do something that is justified by the need to do something that is justified by the need to do something... ad infinitum. We instead just accept that they're free to do whatever there's no reason not to do.
My rejection of justificationism includes that kind of freedom of intention, and to deny such freedom of intention, as in to insist that nobody does anything until it can be shown that there is a good reason to do so, would also qualify as a form cynicism in the sense that I am against here. But my rejection of cynicism also extends equally to a freedom of belief like that put forth by philosophers such as Kant and Popper. I say that it is not irrational to hold a belief or an intention simply because you are inclined to do so, for no reason; it is only irrational to continue to hold it in the face of reasons to the contrary.
But in rejecting justificationism, I am not at all rejecting rationality, or the importance of reasons. I am still against dogmatism, as I have previously argued; against irrationally holding opinions in the face of all reasons to the contrary of them, or asserting them to others with no reasons to back them. I only hold, for the reasons I have shown, that such an anti-justificationist position is the only practicable form of rationality, the only one that leaves us with reasons from which to reason.
Justificationism, if true, would make it impossible to ever rationally hold an opinion, instead insisting either that we hold no opinions, or else hold some core opinions to be, quite irrationally, beyond question. In rejecting justificationism, we make room to hold some opinions, still open to question, that can nevertheless serve as reasons to hold or reject other opinions.
We do lose any hope of ever having absolute certainty in any of those opinions, as they all remain constantly open to question and revision. But justificationism never offered any hope of rational certainty anyway, only the irrational false certainty of dogmatism (or else none at all). And with justificationism out of the way we can at least begin to compare our tentatively held opinions against each other and progress towards sets of opinions that gradually make better models of both reality and morality.
