“Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end.”
― Immanuel Kant, Grounding for the Metaphysics of Morals/On a Supposed Right to Lie Because of Philanthropic Concerns

“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

“Why are there beings at all instead of nothing? That is the question. Presumably it is not arbitrary question, "Why are there beings at all instead of nothing"- this is obviously the first of all questions. Of course it is not the first question in the chronological sense [...] And yet, we are each touched once, maybe even every now and then, by the concealed power of this question, without properly grasping what is happening to us. In great despair, for example, when all weight tends to dwindle away from things and the sense of things grows dark, the question looms.”
― Martin Heidegger, Being and Time

“Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you.”
― Friedrich Nietzsche
