user: In accordance with existentialism, does life have universal meaning?

assistant: The philosophical theory of Existentialism developed by Jean-Paul Sartre in the 20th century revolves around the idea of no objective purpose to life. 
Life itself has no universal meaning true for all beings. However, according to Sartre, that does not render our existence and actions as purposeless, but it is an encouragement to seek out our own understanding of purpose.
