When we search for the truth with words, we have to assume something in order to be able to deduce something logically. The problem with this fact is that it leaves the idea of “a truth” between the assumption(s) and the deduction.
Instead, this fact means that logic is a merry-go-round with two entrances: one assuming something and deducing something, and the other assuming what the former deduced and deducing what it assumed – the two thus circling around the idea of “a truth”. This is obvious in discrete metalogic, that is, logic of the first order, or logic with numbers, where “single” is ambiguous (or contradictory, depending on aspect) between none and all.
In summary: logic is useful (together with math) to handle life in a practical sense, but it (ie, science) can never rise above this level. It can just produce models of the world that are better or worse, never reach a truth. Such reach is just as impossible as that probability would reach 1.
So, don’t believe particle phycisists, they have not found “Higgs particle”, and understand that cladists’ search for “the true tree of life” is just as vain as particle physicists’ search for “Higgs particle” is. Such things (ie, “Higgs particle” and “the tree of life”) are actually running points of rationality, that is, manifestations of the impossible illusion that rationality is searching, ie, manifestations of the rational God. And, this (“rational”) God is just as irrational as all other Gods are.
