In Chapter 10 of his book Mares defends both the use of Classical Logic by mathematicians and his own use of Classical Logic as a metalanguage for Relevant Logic. It is not totally impossible that I am developing some faint glimmers by way of understanding what he is saying. I probably have...

I found your opposition/skepticism very useful for clarifying things in my own mind (or perhaps for creating the illusion in my own mind that things were clarified); thank you very much. If I understand you correctly, both of the following are true: IF (IF A THEN A) THEN (A depends upon A) and...

FactChecker's comments are also highly useful to me. Let me take 3) first. I don't know if this counts as a formal definition, but a semantics stating a truth condition has been provided for Relevant Implication (see above, and Mares, p. 28). This semantics posits a 3-place relation, R...

General remark: all of the points you make are very useful to me. They are just what the doctor ordered. I have found that when people (or at least my tech colleagues) encounter the paradoxes...or maybe just weirdnesses ... of Material Implication, they say 'Well, there has to be a causal...

(Mentor note: link removed as not essential to the question.) The problem is: what is relevance anyhow? My questions are these: did I get the math right in the following? Is there a better, more acceptable way to lay out the sample space Ω and the two events F and E? Apart from the math...
