Context of meaningfulness: All are in play at once
1) “fore-having: a general grasp of a situation
2) “fore-sight”: we can see in advance the appropriate way in which things can appear
3) “fore-conception”: we grasp in advance conceptually the appropriate way to interpret something (190)
All understanding is therefore circular, because “there must already be a context of intelligibility for any discovery to be made, or for any conclusion to be proved” (192) That is not to say that deduction can only prove what is presupposed—but boundaries (contexts) are defined by each discipline of knowledge in which meaning can function.
