Obviously, an absolute certainty may be impossible and claims of knowledge might remain contestable. However, it is exactly this contestability of claims of knowledge that makes science and liberal democracy absolutely necessary if humans are to achieve peace and prosperity. What these institutions offer is the capability for continuous reexaminations and an unending train of tentative arbitrations. Foucault did not accord either science or liberal democracy any distinctive significance. Perhaps, he did not appreciate the evolutionary significance of these institutions. However, I do not want to suggest that postmodernism is totally insignificant. There are plenty of critiques of the basic assumptions of liberal democracy, levelled by postmodernists and others. However, on the basis of the thought experiment that I will be running below in this chapter and also on the basis of the discussion in Chapter Seven and even in Five and Six, I will be able to suggest that it is the actual or current liberal democracies and their theoretical conceptions which are vulnerable to the critique of postmodernism. Liberal democracy can be conceived as an institutional response to the need for arbitration between moral ideas and this can be quite immune to the critique of postmodernists.
The second premise of my thesis is that if knowledge could effect power we should, under certain circumstances, namely being a human organism, expect conditions of competition through claims of knowledge to emerge and with it the emergence of different forms of response to competition. It does not take a great effort to realise that competition through claims of knowledge is all-prevalent. It is not only the formal ‘who is saying what’ that occupies the literary, scientific and political world with endless controversies, but also the informal talk that people are engaged in.[i] The responses to claims of knowledge take many forms. Among these forms of competition or responses to competition are suspicion, discrediting the claim or even the claimants, making counterclaims, challenging to prove the point, trying to prevent the making of the claim, denying the means to make the claim, or trying to involve other people in giving opinions or to arbitrate.
The third premise is that if knowledge and claims of knowledge can generate power and therefore bring about competition through claims of knowledge then we may be warranted to expect the evolution of institutions that deal with competition. I suggest that institutions such as science, liberal democracy and ideologies are the institutional embodiment of a more systematic response to competition through claims of knowledge. A question might spring up immediately: Why do three different institutions evolve instead of just a single one? Liberal democracy and ideologies, I would suggest, share the characteristic that they both deal with moral or quasi-moral ideas or moral claims of knowledge. Science deals with competition through non-moral ideas. The difference between morality, the subject matter of ideologies and liberal democracy, and non-moral ideas, the subject matter of science, is not that morality cannot be scientific, it is that moral ideas need special circumstances or arrangement for experimentation (see Chapter Five and Six). The difference between liberal democracy, on the one hand, and ideol
