Saylor Academy Open Education Course: Heidegger

I am currently working through this open online course (choose the ‘Unit 5’ for Heidegger) in order to deepen my understanding of Martin Heidegger’s thinking about ‘being’, which is fundamental to my thesis. That's it. An announcement. I'm taking 'care'. 
If I take death into my life, acknowledge it, and face it squarely, I will free myself from the anxiety of death and the pettiness of life - and only then will I be free to become myself. (Martin Heidegger)
