@JLNobody,
logic can never provide an ultimate test: Induction can never exhaust the empirical possibilities and the premises of Deduction are never "proven" just assumed.
There are three kinds of logic. perceptive. philosophical and practical.
If perceptive, it's what you feel about it; if philosophical, it's about descriptive words;
if practical, it's about substance, making things work, proving it works by demonstration, not by words, by deeds.
“What we think, or what we know, or what we believe is, in the end, of little consequence. The only consequence is WHAT WE DO.” John Ruskin (1819 - 1900)
