It’s interesting to realize that nowadays Eastern philosophies, such as Buddhism and Yoga, are in vogue as a way to happiness (and I myself study this knowledge), while most people (me included) are not aware that Western philosophy also addressed the issue of happiness, or “the meaning of life” if you will. All of them seem to agree that it needs to start simply with awareness, consciousness.

As other people have mentioned here, of course the series has a finite number of episodes, and thus misses some important thinkers (Sartre and the whole existentialism, for instance), and maybe some points are under-explored. Nevertheless, it was performed in such a way that the message is clear, and it provokes the interested viewer to look further for the work of these and other great philosophers.
