Heidegger—Time & precedence

"That which is earlier with regard to the arising that holds sway becomes manifest to us men only later. That which is primarily early shows itself only ultimately to men. Therefore, in the realm of thinking, a painstaking effort to think through still more primally what was primally thought is not the absurd wish to revive what is past, but rather the sober readiness to be astounded before the coming of what is early."
