Perhaps, but from a scientist's point of view that still does not quite account for the breakdown in communication between the cultures. Two other factors immediately come to mind, both having to do with the way the study of humanities has developed in recent years. Scientists, who must work together in research teams if they are to succeed, are made uneasy at the prospect of being drawn into these wars. The other tendency among modern humanists that disturbs many scientists is what I am inclined to call the deconstructivist tendency. I confess to not knowing a great deal about it, but from the outside it seems to deny the possibility of ever reaching certain or positive knowledge about the world.
Scientists have a problem with that.
One could write a book on the so-called cultural wars, and several people have. On one level, they are the result of very much the same kind of protest Snow was making about an entrenched literary culture, the values of which seemed to him to depend more on class prejudices than on rational inquiry. That these wars have not broken out in the sciences probably has a lot to do with the standards of proof required of research in scientific disciplines. And all these words are fighting words likely to lead to rancorous public debate. On the other hand, one could also make the point that science's innocence of cultural wars has to do, in some degree, with sociological conditions, which until recently discouraged women and minorities from pursuing careers in science.
