Conceding this leaves but a short step to hierarchical thinking of a sort that is at present inadmissible in most liberal discourse. Wherever there are right and wrong answers to important questions, there will be better or worse ways to get those answers, and better or worse ways to put them to use. Take child rearing as an example: How can we keep children free from disease? How can we raise them to be happy and responsible members of society? There are undoubtedly both good and bad answers to questions of this sort, and not all belief systems and cultural practices will be equally suited to bringing the good ones to light. This is not to say that there will always be only one right answer to every question, or a single, best way to reach every specific goal. But given the inescapable specificity of our world, the range of optimal solutions to any problem will generally be quite limited.
