The sociologist and philosopher Frédéric Lenoir presents Friday in "It feels good" his new book entitled "Just after the end of the world".

He explains to Anne Roumanoff's microphone why he considers that the spirit of competition between humans leads to what he calls in his book "the disharmony of the world".

INTERVIEW

"In our relationship to the world and to others, let us always seek justice and harmony. These are the two beacons that must illuminate all our actions".

This sentence, which may be useful to future candidates for the baccalaureate in philosophy, is taken from 

Just after the end of the world

, Frédéric Lenoir's new book.

The sociologist and philosopher, guest on Friday of the program

"I think that a world in which we all seek justice and harmony would be a perfect world", confirms Frédéric Lenoir on Europe 1. "Except that indeed we are in a world where there are a lot of injustices. And we are in a world in which rivalry and competition create disharmony. "

4 pansy weeds

The philosopher identifies four weeds that prevent us from living in harmony: the spirit of possession, the spirit of greed, the spirit of lust and the spirit of domination.

"And all this is linked," he says.

"That is, as soon as you own, you compare yourself with others and always want more. You are competing, and this is how the world is being destroyed."

"This is why we have to leave these poisons of the mind and be in something where it is not very important to have", advises Frédéric Lenoir.

"To have what one needs to live well, okay. But to have in order to have, and to have more than others, is what is called mimetic desire."
