The philosophy of cosmicism states that there is no recognizable divine presence, such as a god, in the universe, and that humans are particularly insignificant in the larger scheme of intergalactic existence, and perhaps are just a small species projecting their own mental idolatries onto the vast cosmos. This also suggests that the majority of undiscerning humanity are creatures with the relative significance of insects and plants, when compared to the universe.
The most prominent theme in cosmicism is the insignificance of humanity. Cosmicism shares many characteristics with nihilism, though one important difference is that cosmicism tends to emphasize the insignificance of humanity and its doings, rather than summarily rejecting the possible existence of some higher purpose (or purposes). For example, in Lovecraft's Cthulhu stories, it is not the absence of meaning that causes terror for the protagonists, as it is their discovery that they have absolutely no power to change anything in the vast, indifferent universe that surrounds them. In Lovecraft's stories, whatever meaning or purpose may be invested in the actions of the cosmic beings is completely inaccessible to the human characters.
Lovecraft's cosmicism was a result of his complete disdain for all things religiousexistential helplessness in the face of what he called the "infinite spaces" opened up by scientific thought, and his belief that humanity was fundamentally at the mercy of the vastness and emptiness of the cosmos. In his fictional works, these ideas are often explored humorously ("Herbert West–Reanimator," 1922), through fantastic dream-like narratives ("The Dream Quest of Unknown Kadath," 1927), or through his well-known Cthulhu Mythos ("The Call of Cthulhu," 1928, and others). Common themes related to cosmicism in Lovecraft's fiction are the insignificance of humanity in the universe and the search for knowledge ending in disaster.
