Roget’s II (, Merriam-Webster Thesaurus, Visuwords


Cosmos is the universe regarded as a complex and orderly system; the opposite of chaos. The philosopher Pythagoras used the term cosmos (Ancient Greek: κόσμος) for the order of the universe, but the term was not part of modern language until the 19th century geographer and polymath, Alexander von Humboldt, resurrected the use of the word from the ancient Greek, assigned it to his multi-volume treatise, Kosmos, which influenced modern holistic perceptions of the universe as one interacting entity. — Wikipedia



The size and age of the Cosmos are beyond ordinary human understanding. Lost somewhere between immensity and eternity is our tiny planetary home. In a cosmic perspective, most human concerns seem insignificant, even petty. And yet our species is young and curious and brave and shows much promise. In the last few millennia we have made the most astonishing and unexpected discoveries about the Cosmos and our place within it, explorations that are exhilarating to consider. They remind us that humans have evolved to wonder, that understanding is a joy, that knowledge is prerequisite to survival. I believe our future depends powerfully on how well we understand this Cosmos in which we float like a mote of dust in the morning sky. — Carl Sagan, Cosmos
