Quote by Arthur Schopenhauer
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.
Summary
This quote suggests that any absurd idea or belief can be rooted in the human mind, as long as it is introduced before the age of five and repeatedly reinforced with seriousness. It emphasizes the vulnerability and malleability of young minds, indicating that early exposure and constant repetition of certain concepts or ideas can lead individuals to accept even the most irrational or nonsensical notions.
