[Lloyd Gillespie]

Wikipedia lists over 137 different types of logic, and 9 categories. Not all are mathematical. There is predicate/subject, two, three, four value logic, on and on. All mathematics and logic is real, as it is not a construction as you suggest, they are of our innate, intrinsic essences. All maths and logics must first be cognized from the outside world as objects and symbols, only then do we abstract them into our perceptive memory areas. So, at base math and logic are as real, and directly cognized real, as any other aspect of our innate selfs. The post-modern view is not correct. The older classical Ocham's razor view is the valid one, and Heraclitus is more right than all of them, with his open natural dynamic logic, and logos.

"If that is not the case, then logic & reason become the father & the mother of all sorts of relationships.... is it so? Can the one live absolutely devoid of the other?"

Nothing lives absolutely devoid of the other. As I said, they should not be as closely allied as post-modernism has falsely taught. Both reason and logic are agents of our one essence, thus live in the same house. It's just that confusing or mixing them improperly makes no sense, and does harm to your own true reasoning and logic self. And, beware the subjective illusion, as tis worse than the objective illusion. And finally, to think logic is reason, is just plain academic ignorance. As a child, I had logic long befor reason - natural instinctual logic. We all did.
