A famous monologue from Shakespeare's As You Like It begins: "All the world's a stage, And all the men and women merely players; They have their exits and their entrances, And one man in his time plays many parts" Which theory of social life could be seen as taking its inspiration from these lines?

Society, in general. In essence, Shakespeare aims to say we are all just pretending in front of other people, like a facade. We will have our moments and our downs. The "one man pays many parts" can be how a person can pretend to be something they are not to get others to like them. Like trying to fit in one group, you'll pretend to be into what they are or etc. Can be applied in the dating scene, friendships, work and other forms of social life.
