The words 'reason' and 'rational' are semantically linked, and I suspect that many statements of the form "[antecedent] is a reason for [consequent]" are intended to convey something like "given the (assumed) truth of [antecedent], there is a rational argument for [consequent]."

In ordinary usage, it is commonplace to leave out what seem to be obvious antecedents, and in the phrase "Alex had a reason to avoid being set on fire", they are completely missing, but we can guess that Alex desires to avoid pain. This, however, does not yet yield a valid argument; for that, we have to add further premises, such as that Alex believes that being set on fire would cause him pain.

In this view, the statement "we have reasons to avoid pain" is more-or-less tautological, given that pain is practically defined as sensations which induce strong desires for their avoidance.

I feel this gives us a way to analyze "gives/has a reason" talk which conforms to your distinction between reasons_reducible and reasons_irreducible, and furthermore justifies your rejection of the latter: reasons_irreducible turn into arguments without even tacit premises, which is to say they are not well-formed arguments at all (or maybe they are question-begging ones; I am uncertain about which fallacy best captures their problem.)

Nice read, and agreed with your conclusion. For me, it's useful to think of reasons as acceptable answers to why-questions, whether those be causal explanations, normative assertions, or anything else.

This framing makes it easier to explain good vs. bad reasons, and conditions under which we say there are no reasons, or that something is *the* reason.

It also supports the intuition you develop in your argument re: the weirdness of believing in reasons simpliciter. They're more productively thought of as handy but humble approximations of longer-winded responses.

The important part, though, is that reasons presuppose dialectical contexts. We wouldn't use/reference them otherwise.
