This line of reasoning on its own is weak, because there is no reason why a neurovascular coupling change could not selectively alter task-evoked signalling to the vasculature without affecting resting state blood flow.
This characteristic, of course, is one that modal logic shares with most traditional and modern logical theories; the connection with everyday reasoning is rather weak.
Our experiments show that both performance and accuracy of botnet detection can be greatly improved by the active evidential reasoning, especially when the evidence is weak, hidden or lost.
Although the theoretical reasoning behind the incitement of male-male competition and the paternity-confusion hypotheses is sound, the desired empirical support is weak, especially for chimpanzees.
Another, although much weaker reasoning is that in Equations 4 to 5, the ∫ρ[1 + a/(3j)]d r1 ≈ G(x ≡ 1 + a/(3j), N) = N x /5 approximation can be used, which originates from the crude ∫ρ[1 + a/(3j)]d r1 ≈ (∫ρd r1)[1 + a/(3j)] = N x, and one can find more detailed discussion and more forms in [4] for G.
This reasoning is in accord with the weak electron densities observed for the arylamine base in the active site of T7 DNA polymerase, where the authors of the previous study also concluded that conformational heterogeneity may hinder the insertion of an incoming nucleotide.
Perhaps the weakest link in Dr. Olson's reasoning is the supposition that Chaucer knew about the rare event, since it occurred around the year of his birth.
Although this line of reasoning has received much criticism, it is arguable that a weaker, and so less vulnerable "negative" line of reasoning is really behind much of luck egalitarianism (see, for example, Arneson 2001).
Bernard Williams' "relativism of distance" (Williams 1985) and Ian Hacking's (1982) defense of variability in styles of reasoning are instances of weak relativism.
