This is the closest philosophy to my own that I’ve come upon thus far, and I think what it requires is a moral framework based on Bertrand Russell and Sam Harris that helps guide the existential creation of our own meaning frameworks.
While the original term applied to the search for meaning, I think it can and should be applied more broadly.
I would expand Camus’ definition to mean, “The irreconcilable conflict between human experience and underlying reality.”
Camus’ original search for ultimate meaning is contained within this because it’s something humans yearn for as part of their experience, yet it’s unattainable. But there are many other examples of this as well, which I explore in How Absurdism Applies in Everyday Life.
Some examples include:
Love surviving the scrutiny of neuroscience and evolutionary biology
Trying to “be a better person” when you realize free will is an illusion
And ultimately, willing the world to be any different than it is
These are all collisions that advanced humans cannot avoid, because knowing the underlying truth behind these sensations does not stop us from experiencing them.
Absurdism, then, is precisely this collision of experience and reality—and the choice to enthusiastically embrace our humanity despite knowing the truth.
This is the rebellion that Camus advocates.
