 Hegel believed that human understanding follows a path of  Thesis – this is why things happen they way they do  Antithesis – the thesis fails in some important ways, here’s a better explanation  Synthesis – the antithesis rejected too much of the original thesis, here’s a better hybrid explanation that captures the good from both thesis and antithesis 5
