• We declare that only man exists. This is not to say that material, inorganic nature and nonhuman beings-animals and plants-are in any sense unreal, insubstantial, or illusory because they do not so exist. We merely state that the reality of these nonhuman realms differs from that of human existence, whose primary characteristic is Da-sein (literally being-the-there)... Man as man is present... in a manner wholly different from... inanimate things.
