Have only read 3 quotes of it and it may already be one of my favorite books ;)
Tears came to him. He wept quietly, holding nothing back. He mourned mankind, and the blindness of men, who thought that the Kosmos had rules and limits that would shelter them from their own freedom. There were no shelters. There were no final purposes. Futility, and freedom, were Absolute.There’s a universe of potential, Lindsay, think of that. No rules, no limits. Life moves in clades. A clade is a daughter species, a related descendant. It’s happened to other successful animals, and now it’s humanity’s turn. The factions still struggle, but the categories are breaking up. No faction can claim the one true destiny for mankind. Mankind no longer exists.
