It has much to do with mathematical logic. Do you miss John Jones or something?

I was, in effect, just noting that your tedious little essays have at best a very tenuous connection to logic as a technical field. -- Aatu Koskensilta (aatu.koskensilta(a)uta.fi) "Wovon man nicht sprechen kann, dar�ber muss man schweigen" - Ludwig Wittgenstein, Tractatus Logico-Philosophicus

If you have read Copi's Introduction to Logic as many years as I have in its various editions, when the symbolic logic comes to an end, the final third of the book is about inductive logic, analogy, probability and theoretical aspects of the scientific method. I just figured that anything in that book is acceptable especially in sci.logic. From you now I get the impression that when in here we should focus upon symbolic logic. > -- > Aatu Koskensilta (aatu.koskensi...(a)uta.fi) > > "Wovon man nicht sprechen kann, darüber muss man schweigen" > - Ludwig Wittgenstein, Tractatus Logico-Philosophicus |
