Habermas (1971) has argued that insofar as science is engaged in its own project (i.e., Kuhn's normal science), it cannot examine the social preconditions of its own existence. Rarely does it become possible for the scientist to step back, examine the social preconditions that have led to the construction of the mask of theory, and ask: Why have I interpreted the natural world the way I have? What elements of my culture made one interpretation obvious and believable, but not another? Habermas notes that asking these questions is a function of critical reflection, a type of thinking related to, but different from, science as such.
As cultures change it becomes possible for scientists to ask these questions, to be self-critical about our presuppositions. Recently, Western culture has shifted in striking ways. We live in times characterized by critical self-examination. Our cultural matrix has us ask "What does this say about us; what would future generations think of this?" with the same rapidity as the Greek shepherd might have asked, "What is this an omen of; what do the gods mean by this?" Living in a time of critical self-examination offers working scientists a window of opportunity, a chance to see how some previously invisible biases have affected the construction of one mask of theory and weakened our view of the face of nature. Competetive individualism is one such bias. Gender bias is another.
