There are many types of magnets, all composed of selective material such as alluminum, nickel. cobalt. iron, boron, rare-earth element neodymium, and the rare-earth element samarium. What do magnets? Well depends on the magnet, but generally the same components of magnets. Objects consisting of the same material, pulling towards one another. The Law of Attraction.
Just because you found "meta-physics" and describe it as a faceful of non-science, does not mean what was present is untrue. Herbal Medicine/alchemy practiced by Tibetan Monks has been around since before recorded history. Modern day science is recognizing more and more the practices of hollistic medicine. Does smoking weed invoke spiritualism, or fight cancer? Im pretty sure its different for everyone.
How we use words does matter. You view of "non-science" or meta-physics is narrow. Discredited, if you will.
The pavement outside, prevents the grass from growing, i need not go into the circle of life to see how this will affect evolution. Its is a monument to the wishes of humans. We have not always had such excellent means of transportation. I dont want to walk the Desert.
The fact of the matter is HUMANS EXIST on earth. Humans think and have a reasonable and motivational cause for action. We do influence everything whether we posses the capacity to see such is another story. Without the wheel, there woul be no cars. Without cars? Perhaps no impending environmental doom. aka effected atmosphere. With a big enough hole in the atmosphere radioactive solar particles will hit us directly. Cancer? Disease? Who knows, but the fact of the matter is we are our own worst enemy. We have affected ourselves and our evolution. So much so that we are at a turning point in human history.
