'Do you suppose that Shakespeare wrote for a specific audience, Bach, Beethoven? Did Michaelangelo sculpt for a specific audience?'

Interesting point; in the sense that all of the above had either employers, were commissioned to produce specific works or had to take account of political or other pressures upon them I think it can be argued that they most definitely produced their work for a specific audience. This is not to deny their genius and to recognise the reality of their situation does not deny the fact that their art transcends its origins.

If you believe that Darwin published with a view that his work would enjoy general consumption I suggest you check out the publishing history of his work. Of course he was writing for a specific audience, namely those people who had a grounding in and knowledge of natural science (as it was known). That is evident in the assumptions that he makes in his writing of specialist understanding on the part of his readership.

With regard to your apparent lack of knowledge of scientific method I need do no more than refer you to your various interchanges with Snail in which you appeared to be ignorant of the principal of falsifiability or to understand the difference between observed phenomena and a theory constructed to explain such phenomena.
I could also point to your inability to read documents accurately (Ruse and other science witnesses) but that might be seen as a cheap shot.
