Science is merely the art of observation, of weights, measurements and hypothesis. It is in fact the lowest order of knowledge, metaphysics being of the highest.
Natural science can tell us nothing about anything it cannot see, touch, hear, etc. Nor can it tell us anything about events that occured before life, consciousness and time even existed. If it presumes to say something about these events it has encroached into metaphysics.
An interesting but extremely odd point of view, IMO.
I quite agree that science is often perverted in today's world into scientism, in which proponents of various ideologies attempt to use science to promote their ideas in realms where science is not applicable.
But the scientific method is the only method we (presently) have for knowing anything on the "fact" level, as opposed to the speculation or faith level.
I can (and do) believe in things that aren't demonstrable facts, as such, but I cannot really have any logical reason for expecting others to do the same. And science is the only method we have available for demonstrating facts to be such.
IOW, we can demonstrate by repeatable experiment that gravity is a fact. We cannot demonstrate the existence of God or his nature to the same level of factual certainty.
While I don't rank these various types of belief, I think it odd to claim that the only one we can demonstrate to be true is the "lowest" on the scale, while those supported solely by mental gymnastics are the "highest."
