Having studied abstract algebra, I disagree that the soul of lisp is abstract algebra. You're not really actively thinking algebraically when you're writing lisp, not in the same way that other languages have you "actively thinking about category theory". There are also other modern FP languages that are "basically lisps", like Julia or Elixir, that would be hard to call "algebraic".
