One the greatest french writer once said If God did not exist, it would be necessary to invent him." It's a great line that goes back to Voltaire and it's often mischaracterized as an atheist quip about the fact that people will believe in anything. When in fact Voltaire was arguing the exact opposite. Voltaire believed that believing in God was beneficial to society.
In fact, when he wrote, if God did not exist, it would be necessary to invent him, he was essentially arguing that even if there was no God, that it would be good for society to pretend that there was one, to have something to believe in. And this is similar to Lacan's analysis of Dostoevsky's famous passage about, if God exists, then nothing is permitted. Lacan says that it's the exact other way around, that it's precisely because God exists that everything becomes permitted. That God, as a kind of master signifier, or in psychoanalytic terms, a big other, allows people to shape and structure their own morality and their own ethical principles. And that even if there weren't a God, you would believe in something else, like money or the ideology that you follow. And so Voltaire's idea that if God did not exist, it would be necessary to invent him, contains a deeper truth that goes beyond religion as such, which is that the idea of God is how man creates an idea of himself.
And even in a society characterized by the decline of the belief in God, man can’t help but erect his own tower of meaning. Something will always fill the vacuum left behind by religion, whether it is money, ideology, science, or nationalism. Voltaire’s realization is thus not a matter of theology. It appeals to the most basic human impulse: the need to situate life within a higher principle and bestow meaning on it, one that frames our destinations, purposes and ethics. This idea of God is not just a matter of faith; it regards the way humanity sees itself and its place in the world. Even in an time that we've many going, the need for something greater than ourselves remains as strong as ever.
We are definitely in an era where people believe in anything, of course, we have our free will. But for me, I believe God exist and no one can make me believe otherwise.
