@Frank Apisa,
Olivier: 1. This world exists. Deal with it.
Frank: That is a "belief?" I thought you have been asserting it is not.
O: what part of 'I believe the universe exists' don't you understand?
------
O: 2. Logic works.
F: That is a belief? C'mon.
O: how else would you call it? A guess?
---------
O: 3. The scientific method is the best known way to understand the world.
F: That is a belief?
Next you will put down "onions"...and declare that to be a belief also.
O: onions are part of the universe, and so is science, so they bothh assume #1 is true. A belief in science being generally trustful in spite of being generally falsifiable is healthy. It's part of my value system, and it implies a trust in reason. A leap of faith that reason can help model the world.
----------
O: 4. Any onthological or theological discussion is ultimately futile.
F: That is just plain false.
O: nope. It's a consequence of the true essence of reality being beyond our reach. Same apply to most metaphysics.
------------
O: 5. Determinism is probably false.
F: How on Earth can you consider that valuable???
O: allows free will and justifies all our laws, via the concept of personal accountability.
