Knowledge, purpose and pleasure
Why does knowledge bring pleasure? Why is it thoroughly possible and right to revel in a statement of fact? If something is, it just is (once you know it). What is exciting about that? Why, when it comes down to it, is the understanding of "A is A" so fantastically marvelous?
Certainty. The Law of Identity brings certainty. When you know what something is for sure, you can count on it as a touchstone and base for knowledge, and this makes possible a whole proceeding network of possibilities available for construction as desired. And what is desireful construction but hope incarnate? Reason to be joyful, indeed.
Purpose as organizer: Purpose structures, sifts, sorts experience according to a standard, making it, at once, more readily intelligible and more immediately useful, being practically pre-applied to a goal. Thus knowledge newly acquired becomes automatic progress, of a sort, towards one’s eagerly anticipated goals. A nucleating grain of purpose in a super-cool information pool, precipitates order about itself, making tangible and cognitively graspable the former - and unbearable - incorporeality.
