The claim that life is absurd admits of a happy or an unhappy construction.
To say that something is absurd means the same as to say it is ridiculous or worth laughing at. In other words to say life is absurd is to say it is like a joke.
But there are jokes and jokes. Some jokes are cruel. So, for example if I am invited to a party and asked to play hide and seek, and I hide, and the guests don’t find me but go off onto the balcony to drink white wine and laugh about what a loser I am, that would be a cruel joke. If life were like that t would be an unhappy state of affairs.
Not all jokes are cruel. If I show up at my house and a friend of mine says that nobody remembered my birthday and says you know what, why don’t you go to the pencil store and get a pencil to write a letter to them complaining, and then when I get to the pencil store it’s been decked out for a surprise birthday party for me, that’s a kind joke.
Is life absurd in the bad way or the good way? Who knows. Heidegger says somewhere that man is the poem sung by Being. Maybe man is the joke told by Being. The point being that just because it’s absurd doesn’t mean we should cry about it.
