Abstract
In a postmodern culturism, everything is relative, in this way, nothing can be affirmed as absolute truth. Taking into account that culturism is the belief that some cultures are superior than others, this essay proposes the idea that a postmodern culturism is the belief, superior to others, that all cultures are to be revered. Within a postmodern culturism, the essay proposes the analysis of three common arguments through a specific epistemological perspective, rationalism: empirical data and the primacy of reason. The analyzed arguments are: first, all cultures ought to be equally revered; second, western logic is different to the ancestral logic; third, all ancestral cultures have wisdom. The article concludes that these arguments do not withstand the rational analysis.
