In Sein und Zeit, his magnum opus, Heidegger analyzed anxiety (angst). In The Fundamental Concepts of Metaphysics, he analyses boredom - but this is only discussed in Chapter 1, which we aren’t reading.
In Chapter 2, he turns to a different line of questioning - the question of world.
Umwelt - environment - Uexkull.
The first path one could take to understand the world is to analyze the word’s etymology.
And he says, finally - p.177 final paragraph - third path, the path of comparative examination. Neither the historical, nor the phenomenological path (the path as everyday dealings, from Being and Time).
Man is not simply part of the world, but controls it and stands above it - “has” the world.
May be more than three paths but
Start and move towards absolute truth
The animal has less world, has less access to things, [how lol?]
