Usually when we speak of the “meaning of life” it has hints of religion associated (or at least Monty Python). The rather abstract question, however, has some very concrete elements based in science. What is the context in which we find life? How do living things relate to one another and to their environment? Our philosophy – particularly our notions of how we know things and what things are talking about – allow us to tie these basic empirical questions into a greater understanding of the universe and ourselves. The talk will explore where the lines are between science, philosophy, and fundamental meaning, particularly in regards to how we define “life.”
