Being and Time is notoriously difficult to read. And at base, it sounds so simple-what does it mean to be- well being there is to be a caring thing in the world. The world and you co-exist, without you, there is no world, and without the world there is no you. It sounds like solipsism and in the hands of a lesser thinker- it could easily be dismissed as such but Heideggar instead uses the concept of time to examine how we are thrown into existence already pre-determined in a way by our nationality, language and physical make up; we are fallen in the sense that we are alongside other humans and co-exist within laws, rituals and cultures ; and are existentially oriented-meaning we see that we have choices before us leading towards our demise. Past, present and future create the framework for us to understand ourselves. The question is then-what does authenticity mean for a creature such as us.
