[S]imply rejecting a whole class of methods is not just a logical error — it is a political one as well. Anyone who cares about society, about social and environmental justice, about peace, and who is committed to democracy, cannot give up on the idea of science. Humans are intentional and social actors. If we do not accept some standard for valid knowledge, we cannot agree on how to proceed. If those critical of existing social arrangements reject any basis for valid knowledge, they cannot make politically effective claims about where and how change needs to occur. If critical researchers say that science is nothing but ideology, why should we bother to listen to any social scientist, incuding them?
