In 2020, evolutionary biologist Gad Saad published his The Parasitic Mind: How Infectious Ideas Are Killing Common Sense. He describes how in the postmodern Western world many ideas gradually arose that received a dogma-like status, that can only be criticized or renounced at the cost of being censured or even cancelled. In fact, Saad views these ideas presenting themselves as uncontradictable axiomatic principles as idea pathogens, comparable to how viruses and other parasites invade their hosts in order to take control of it and eventually destroy that host. Those who do conform, lose their freedom of thinking through being invaded and taken over by these pathogens. Those who do not conform, similarly lose their freedom of speech by being silenced and de platformed. However, Saad sees opportunities to use multi-stranded reason derived from as many diverse disciplines as possible (logic, history, different cultures, biology) to stimulate a philosophical immune system that will fight these idea pathogens. In this paper I will compare idea pathogens mentioned in the canonical texts of the Hebrew Bible and the way these texts fought these pathogens, to the ideas Saad mentions as mind-parasites in the modern and post-modern worldview and his way to address the problematic nature of these ideas.
