Mr Shaw, I have developed a respect for your knowledge and intelligence through reading your posts but I cannot agree that objecting to your use of the word 'truth' is nit picking. I can understand your resentment of Snail's sometimes heavy handed condemnation but I am convinced that you are able to see that the use of that word implies incontrovertibility which runs counter to scientific method. In consequence use of the word 'truth' in a scientific context would require so much qualification as to make it pretty meaningless. I have no doubt that you are able to rephrase your evaluation of evolution in such a way that pedants (such as myself) could accept it without question and you could bring your intellect to bear on questions more worthy of it.
