Lots of things to say about this wonderful book. Here's one:
Feelings make a philosophical commitment possible – and we are all philosophers. To have any sustained views on how the world works, what is at play in its dynamics, what we can expect of people, is to make one a philosopher. From this we see that our existential feelings, the Heideggerian 'mood' we are in (a combination of our germinal complex, RIGs, noöforms, and, duly spun, our ongoing personal experience) allows or disallows a particular orientation to the expectable world, i.e., constitutes our own assumptive worlds, which may or may not be happily commensurate with the empirically expectable world.
Therefore, it is the quality of each person's assumptive world that matters, because this will act not only as a filter through which individual experience is refracted, but as the very ground of being that founds what the person is set up and able to perceive. For example, someone must be made capable of perceiving the trustworthy before they can trust.
