"There is no absurdity so palpable but that it may be firmly planted in the human head if you only begin to inculcate it before the age of five, by constantly repeating it with an air of great solemnity"

This quote by Arthur Schopenhauer is an alerting about the power of brainwashing. He is recommending that if a person is exposed to a particular concept or belief from a young age, it can become securely rooted in their mind, even if it is a ridiculous or irrational belief. He is highlighting the significance of mentor children from a young age, as their minds are more impressionable and open to originalities. He is likewise warning versus the risks of brainwashing, as it can result in people thinking in concepts that are not based in reality. He is suggesting that if we wish to raise children with a healthy and balanced worldview, we must beware to not impose our own beliefs on them, but rather to motivate them to think critically and form their own viewpoints.
