Right, so not much a philosopher, but I think you're onto something here. From where I'm sitting, belief isn't a fixed, unchanging constant. It evolves over a lifetime, changing as different life lessons educate us - growth of wisdom, and all that?

While I may have the same core tenets that I did at twenty, there's an awful lot of things have changed, to a greater or lesser extent, over the course of twenty more years. I think lady songsmith is certainly onto something when she notes age, mindset and mental maturity. From personal experience, I can attest that it's far easier to sit in some smug certainty about the rightness of your beliefs when're younger and have less exposure to life
