It is in the field of education that the harmony of mind and nature is evident.  A good thought is a good teaching, even, or particularly, as far as the impact it will have.  Einstein's greatest observations are especially applicable to education.  His lessons are something worth teaching, worth absorbing, a lesson of the highest physics applicable to daily life of time and observational point of view.  By Einstein's own observation, a beautiful theory stands a good chance at capturing truth in its lens.

Makes you wonder about Jesus and Buddha.   What will win the Nobel is first a beautiful teaching, not the complex parsing of thoughts of the hyper specialist, the complications of higher education's specialization. (The dead end of the latest, the newest, in deconstructive... blah.)

Everything is rooted in nature, knowable, perceivable, as much to the child and the idiot as the highest member of society.  (Why we love filmmakers.)  Thus, the great error in assuming that in thinking we have to launch a hostile attack on reality, or that understanding reality is tragic.  And if you think that way, you will lose.

Access to great thought is simple and straightforward.  Too bad that some moral codes appeal to the dark side, the angry cop.  Education is felicitous, even in its hangovers.  Access to knowledge is simple, just act like a poet or a naturalist.

So how sufficient and sustaining a good thought is.  Be your own naturalist, like Ernest Hemingway making observations of fish in streams.  (One of the redeeming qualities of poor Fredo Corleone.)
