p.5 everything healthy is related to health, inasmuch as it preserves or restores health or is a sign of health

p.43 Hegel finally defines "Being" as the "indeterminate Immediate,"... The concept of "Being" is undefinable.

p.50 Being is always the Being of a being. [JLJ - become a philosopher and get paid to crank out statements like this. My attempt at philosophy: Thinking about thinking can make your thinker think better, I think. What about: Living is always the Living of a liver. Or: Looking is always the Looking of a looker. Maybe I have a career in philosophy.]

p.51 Fundamental concepts are determinations in which the area of knowledge underlying all the thematic objects of a science attain an understanding that precedes and guides all positive investigation.

p.131 Man clings to what is readily available and controllable even when ultimate matters are concerned.

p.146 What in truth is the thing, so far as it is a thing? When we inquire in this way, our aim is to come to know the thing-being (thingness) of the thing. The point is to discover the thingly character of the thing.

p.311 Questioning builds a way... The way is one of thinking.

p.369 We come to know what it means to think when we ourselves are thinking. If our attempt is to be successful, we must be ready to learn thinking.

p.370 In order to be capable of thinking, we need to learn it. What is learning? Man learns when he disposes everything he does so that it answers to whatever addresses him as essential. We learn to think by giving heed to what there is to think about... thinking properly takes place in philosophy.

p.371 Most thought-provoking in our thought-provoking time is that we are still not thinking. [JLJ - how profound. I must contemplate the implications of this fact that we are not thinking. I *thought* that I was thinking. I must think about what I was doing, if I was not thinking. The implications of me not thinking are astounding, and I must spend days contemplating that profound thought.]

p.373 Science does not think. This is a shocking statement.

p.374 we moderns can learn only if we always unlearn at the same time. Applied to the matter before us: we can learn thinking only if we radically unlearn what thinking has been traditionally.

p.375 Something which in itself, by its essential being, is pointing, we call a sign. As he draws toward what withdraws, man is a sign.

p.380 We are trying to learn thinking... it is a craft, a "handicraft."

p.381 only when man speaks, does he think - not the other way around, as metaphysics still believes... To be capable [of thinking] we must before all else incline toward what addresses itself to thought - and that is what of itself gives food for thought.

p.381-382 the reason [that we are still not thinking] is that this most thought-provoking thing turns away from us, in fact has long since turned away from man.
 And what withdraws in such manner keeps and develops its own incomparable nearness.
 Once we are so related and drawn to what withdraws, we are drawing into what withdraws, into the enigmatic and therefore mutable nearness of its appeal. Whenever man is properly drawing that way, he is thinking - even though he may still be far away from what withdraws, even though the withdrawal may remain as veiled as ever... Socrates did nothing else than place himself into this draft, this current, and maintain himself in it.

p.382 When man is drawing into what withdraws, he points into what withdraws. As we are drawing that way we are a sign, a pointer. But we are pointing then at something that has not, not yet, been transposed into the language that we speak. It remains uncomprehended.

p.384 What is it that directs us into thought and gives us directives for thinking? ...That which directs us to think gives us directives in such a way that we first become capable of thinking, and thus are thinkers, only by virtue of its directive.

p.386 In the widest sense, "to call" means to set in motion, to get something under way

p.390 What calls on us to think demands for itself that it be tended... by thought. What calls on us to think gives us food for thought.

p.403 [Wilhelm von Humboldt] Language, grasped in its actual essence, is perpetually and at every moment something transitory.

p.410 What unfolds essentially in language is saying as pointing.

p.431 Questions are paths toward an answer.

p.439 In his work published in 1913, Ideas toward a Pure Phenomenology and Phenomenological Philosophy, Husserl devoted a special section (24) to the determination of "the principle of all principles." "No conceivable theory can upset this principle," says Husserl.
  "The principle of all principles" reads:

... Every originarily giving intuition [is] a source of legitimation for knowledge; everything that presents itself to us in the 'Intuition' originarily (in its bodily actuality, so to speak) [is] simply to be accepted as it gives itself, but also only within the limits in which it gives itself there...

p.442 Goethe notes (Maxims and Reflections, no. 993): "Look for nothing behind phenomena: they themselves are what is to be learned."

p.443 What is evident is what can be immediately intuited... The beam of light does not first create the clearing, openness, it only traverses it... the light of reason... does concern the clearing... it needs it in order to be able to illuminate what is present in the clearing.

p.449 [Aristotle] "For it is uneducated not to have an eye for when it is necessary to look for a proof and when this is not necessary."
