So many things which once had distressed or revolted him — the speeches and pronouncements of the learned, their assertions and their prohibitions, their refusal to allow the universe to move — all seemed to him now merely ridiculous, non-existent, compared with the majestic reality, the flood of energy, which now revealed itself to him: omnipresent, unalterable in its truth, relentless in its development, untouchable in its serenity, maternal and unfailing in its protectiveness.
