    I don't now how you read "person" or "intelligence" from what I said, but
    force is ok. Force is a physical concept relating to causation. The entire
    enterprise of physical theory is precisely about the "how" in your first
    question. Hence, all of physical theory is your answer; e.g. quantum
    chromodynamics explains the existence of the fine structure constant,
    general and special relativity for the gravitational constant and the
    speed of light, respective, quantum mechanics for Plank's constant , etc.
    For specific macroscopic examples, look at pulsed lasers, planetary
    orbits, soliton formation, big bang universes :-), etc. I would even
    include complexity driven systems such as tornados (i.e.. vortex formation
    in fluids and gasses.), pattern formation in chemicals and crystals, etc..
    I guess everything with some degree of stability, i.e. not rapidly
    transient, exemplifies how "nature" selects its parameters: dynamics!

    Moreover, the complexity paradigm of random fluctuations interfacing with
    physical "natural" law is very persuasive in its ability to explain why we
    see what we see - i.e. the Anthopic Principle. Great stuff isn't it!

    To the fundamental question regarding what is nature, my quick response is
    that nature constitutes that which is not "supernatural" :-). The laws of
    probability, chemistry, physics, etc. compose the realm of natural
    phenomena. I am sure others can give you a better definition; but I think
    you already know the answer and you know how definitions go.

     Please, forgive my presumption, but I get the sense from your questions
    that you are bothered buy natural causation. If so, why so? I see no
    problems?

    Sincerely
    George A.
