And how will you change the way you lead your life now that have discovered your "informed leap of faith?"
That, Prof, is an EXCELLENT question, because it cuts to the heart of what people are searching for on this and other Forums - including those of the "skeptic" community.
Most people, at some time in their lives, come face to face with the two Big Questions: (1) What's it all about? and (2) What happens after we die? The existential fear and anxiety engendered by these two questions forms the springboard for the whole of humanity's scientific and spiritual endeavours.
A small minority of people are fortunate enough to obtain "insider knowledge" on the Big Questions. These are the mystics (including ordinary folk who undergo "awakening" experiences), and near-death experiencers. After their experience, these individuals are certain that they know the answers, and for them, faith is no longer an issue.
These people usually change their lives drastically as a result of something which they now say they know - not believe. Here is an absolutely classic example:
The rest of us do not have these experiences, and yet are haunted by the same questions. Some people look for certainty in answering these two issues. But a control-freakish need for certainty will draw people to any individual, or institution, which claims to offer it. The usual claimants are (unfortunately) Organised Religion and the pronouncements of the Pope or the Mullah, or Materialist Scientism and the pronouncements of Richard Dawkins and James Randi.
But people looking here will be disappointed - when it comes to the Great Questions, neither the Pope nor Dawkins have the faintest idea what's going on - they're just much better than most of us at kidding themselves. (And, more regrettably, kidding millions of wide-eyed disciples who need a "guru" to do their thinking for them.)
So the only rational approach, therefore, is to rely on other people's research and experience, together with our own life experience, to make sense of things, and to come eventually to a conclusion - a "leap of faith", given the available evidence - in full knowledge that we cannot have all the answers.
"How do you change your life, having made your "informed leap of faith"?
The answer is that - usually - you don't. Life goes on much as before. But what you have achieved is peace of mind - at least, as much as one can obtain in our imperfect world. You have a working model - which makes sense to you if to no-one else - of your place within the scheme of things. You use this model to imagine what life is all about, and what happens after your death.
You may decide that your life is all about having as much fun as possible, while passing your genes on to the next generation, and that after your death you turn into wormfood and fade into eternal oblivion. You may decide that you are embodied consciousness, having this "virtual reality experience" as a learning tool, and that after your "death" you go on to further adventures. You may come up with another scenario entirely.
But whatever you decide, it makes sense to you and helps you through the tough times. That is the best that any of us can ever do. And having made this "leap of informed faith", we get on with living our lives to the fullest extent possible.
