Tabula rasa, colloquially know as “blank slate,” is the idea of individuals are born without any mental predilections, so that all of their personality & morality comes from outside educational & sensory experiences; the nurture side of the nature vs. nurture debate. Proponents argue that humans are born without differing psychological traits and that all aspects of one's personality, social and emotional behavior, knowledge, or sapience are later imprinted by one's environment onto the mind as one would onto a wax tablet, hence tabula rasa. Only politics can explain why this obviously flawed argument continues to this day.

Any parents who have had multiple children objectively know this idea is completely debunked; children are their own individual personalities from birth, and exhibit them in sometimes dramatic fashion: shy vs. outgoing, smart vs average, even happy vs. angsty. Twin studies suggest it must have something to do with differing DNA, but even twins show some differences. Though this evidence seems unassailable, the facade is maintained because totalitarianism is justified by the Left if people are a blank slate that are inherently equal in all ways, only molded by the patriarchy into inequality. Consequently, they are justified by the deduction that if people can be made into perfection then isn’t it society’s moral obligation to do so? That’s why they insist everyone must be equal.
