For a field that is deemed cold and inhuman, Sagan is a shining example that the pursuit of science can be driven by passion. Cosmos is not just about distant stars and nebula, but it envelops all fields of knowledge: art, philsophy, history, biology, physics and even religion to show how they are all interconnected. Sagan weaves between these fields to show that from the bleak uncaring coldness of the Cosmos, humanity arose whether for some purpose or not. The fact is, we exist and hold full responsiblity for our future, and perhaps the future of the Cosmos.
