2400 years ago, an illiterate philosopher condemned writing. It will not make the people wiser, he argued, rather—
“It will implant forgetfulness in their souls: they will cease to exercise memory because they rely on that which is written, calling things to remember no longer from within themselves, but by means of external marks.” — The Phaedrus
Socrates had a point. Before the advent of tablets and scrolls, humans exercised a greater capacity to internalize huge volumes of information (for example, imagine reciting ~1,800 pages of scripture from memory, like these priests in Kerala, India)
As writing overtook oral tradition, and type accelerated distribution, people soon forgot what the world was like before books and newspapers.
