The pathogenesis of pemphigus: Controversy vs complexity

Life is highly complex and, as quantum physics would predict, follows the rule of "everything is possible with varying probabilities". Accordingly, science may be sometimes as confusing as political debates, where the same matter is addressed in different and misleading ways even in the absence of a real controversy. The Viewpoint by Ahmed et al. provides a paradigmatic example of a debate about two theories for pemphigus pathogenesis, i.e. "Monopathogenic vs. multipathogenic explanations of pemphigus pathophysiology", both being possible but occurring with variable probabilities (1).
