All people are born ignorant and foolish, or foolish according to the ancient Greek accurate expression. The child is a pure fool. He does not know that he does not know. He has not yet realized the ability to know. When you know nothing, it is difficult to feel unhappy. You cannot create hell without knowledge. The more a person learns, the more he is detached from the natural wisdom with which he was born. Gradually, from the very first years of his life, he turns into a pure "brain". He becomes a complex and complicated being. Thus, every child, while born wise, with knowledge passes into foolishness. And from simple foolishness to complex, to complicated foolishness. But, no matter what, the temptation for knowledge is great. Whoever knows, can manipulate. The computer does not have intelligence, but it has memory. It can hold as much information as you feed it.

The foolish person can become a great scholar, internationally famous scholar, but in essence he is nothing more than a computer. All his knowledge is just information. It is his memory, not his experience.

So, what is knowledge?
