If I were a tree among trees,
a cat among animals,
this life would have a meaning,
or rather this problem would not arise,
for I should belong to this world.
I should be this world to which I am now opposed by my whole consciousness and my whole insistence upon familiarity.
This ridiculous reason is what sets me in opposition to all creation. I cannot cross it out with a stroke of a pen.
– Albert Camus.
