Being & Nothingness
Why is there anything at all?
Existence, Universals, and Being
Metaphysics asks not just what exists but what it means to exist. Do abstract properties like 'redness' exist independently (universals), or only particular red things? Heidegger urged us to recover the question of Being itself, describing human existence as Dasein; a being that cares about its own existence and is defined by finitude. Behind it all lies Leibniz's question: why is there something rather than nothing?
“Why is there something rather than nothing?”
Where this sits in the course
“Being & Nothingness” is lesson 3 of 3 in Being & the Self, a course about the deeper structure: identity, free will, mind, and being.. The lessons are sequenced rather than a menu, so this one assumes what came before it.
Being & the Self is itself one of 18 courses in thinkr. The set opens with what philosophy is, moves through the Stoics and the Eastern traditions, then into what can be known, what exists, how to act and how power works — closing on practical reasoning you can use in an argument this week.
In the app this lesson is followed by 5 exercises that check whether the idea actually landed — and every answer, right or wrong, is explained rather than scored. That is the part a written page cannot reproduce.
