In continental philosophy particularly existentialism, thinkers reject the idea that there are any predetermined or given meanings/values in life, and stresses that we must take up our freedom and responsibility to go and create meaning for ourselves. These thinkers also tend to argue that there is no inherent human nature, or inherent essence when it comes to things such as gender identity.
However I also want to consider opposing perspectives, so I want to know are there secular philosophers who argue that there is in fact predetermined/given meaning and value in life and it's not entirely arbitrary social constructs, that there is in fact such a thing as human nature? Are there secular philosophers who argue for essentialism?
