I try to be a reasonable, rational person but intellectually, I believe absolute certainty is the be death of the mind, so I will very rarely say, or believe something just isn’t so, it can’t be and it isn’t. But refusing to be absolutely certain sometimes appears to others as irrationality… to be willing to say well, it could be, who can know for sure? I don’t believe anything merely because someone tells me it’s so and I don’t refuse to believe something merely because someone tells me it isn’t so. Doubt and skepticism is a two way street and I don’t let others define it for me. I try to weigh the evidence, learn, explore, keep an open and curious mind, think critically and rationally, ... but one thing I’m pretty sure about is that in an infinite and infinitely complex universe there are things, phenomena afoot and at play that we have yet to even dream about, let alone understand and absolute certainty shuts that door for me. I want to go through that door.
