TLDR Existentialism

[we] are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in a perpetual flux and movement.

David Hume, in A Treatise of Human Nature, Book I, Part 4, Section 6, ‘Of Personal Identity’

I’ve mentioned before that a friend once said something that I feel is similar to this: ‘We are nothing but a collection of traits’.

While Hume said it more fancily, and in some way validates the philosophical prowess of my friend, I still like her version best.
