That tomorrow won't be different from today is not a truth, but a condition necessary for any further reasoning to be built upon. Denying it is denying the "truth" behind the hypotheses, not necessarily their logicality. You can say all scientific hypotheses are wrong (just maybe not today) but to claim it to be illogical is beyond me.
Well, this isn't deduction we're talking about, it's induction (since we are affirming the consequence under your given presuppositions). I'm questioning how we can rationally accept any hypotheses as true, yes. It is illogical in the sense of deduction, it is bad logic to assume the PUN b/c it is the logical equivalent to employ the PNN.
