While positing that “only matter exists,” Marcelo Gleiser also contends “that we know precious little, that we are surrounded by questions of such forbidding complexity that our knowledge will always be limited even if ever growing.” Why he finds this a reason to embrace science:
But forbidding complexity does not need to mean divine, or supernatural. Unknowns are invitations, challenges to our creativity. Obstacles are triggers, not stoppers. We go after them using the tools of science and reason with a fervor that, as Einstein remarked, has all the dressings of spiritual devotion.
So, we must rid spirituality from its supernatural prison, make it secular. Spirituality is a connection with something bigger than we are, seducing our imagination, creating an urge to know, to embrace the mystery that surrounds us and the mystery that we are.
This natural spirituality is not a form of mysticism. Mysticism presupposes that knowledge that is inaccessible to the intellect can be apprehended by contemplation or by a union with the divine. Science, at least to me, starts with a spiritual — even contemplative — connection with nature. But then it uses the intellect as the bridge between this connection and the pursuit of knowledge. As it brings together this very human spiritual attraction to the unknown (merely calling it “curiosity” sounds very impoverishing to me) and our reasoning powers, science is a unique expression of our wonderment with reality, of our awe with nature’s grandeur.
