Isn't it a bit ironic, though. Us here on this forum talking as if any of these ideals are anything we are even moderately familiar with.
Buddhism, Christianity, Taoism, all just "thoughts". Nothing more. Good advice (sometimes...I mean some religions teach peace and love but also hate and violence...just look at the Bible for an example).
I think the Eastern "religions" did a much better job of keeping their philosophies less grounded in some invisible sky man view, but in many ways they are just as "hypothetical" as any.
Religion and Philosophy provide many great insights into how to live a "good" life, but the fact that there are SO MANY disparate ideas (should I be a Cynic? Should I be a Sophist? Should I be an Empiricist? Should I be a Stoic? Should I believe that Qi is real? Should I be a Zen Buddhist or some other flavor?) it shows that it is just that: we are trying to understand our thoughts.
It's observation. Observation of the self and others. And it's hypotheses: how to live a "better life". And those hypotheses are tested and rejected as needed. Which is why so many old philosophies (like old religions) are tossed aside.
Science is much the same way. Observation, hypothesis, testing, rejecting. ALL of it is asyptotic approach to "truth" using the most useful tools.
In fact I will go so far as to say that portion of Philosophy that CANNOT be tested and cannot possibly be rejected was not founded by legitimate reasoning.
