The sense of the individual's identity and place in the world does not remain stagnant and has changed radically over the last hundred years

Antiquated notions such as the "white man's burden", the idea that a person has a sense of individual self is relatively new, the idea of going to a psychiatrist or seeking to cultivate one's self are new.

Ideas permeate the air and become public domain, as per the Vilna Gaon story.

A boy born in contemporary times in Meh she'arim, for instance, is a 21st century child despite all attempts to shelter him. So what you end up doing is taking a person of the 21st century and you use 19th century tools to address them. This is contrived and bound to fail.
