I believe

that Science is a belief system. or at least that it is a system of inquiry that is built upon a single belief. and that belief is thatthe universe can be understood and predicted (even Quantam Mechanics is predictable insofar as it follows certain statistical rules). however, just because the Universe has, for the history of Mankind, been predictable, does not necessarily mean that it is indeed predictable. just because there seems to be a certain order in the universe that Scientific inquiry seems to have shown does not necessarily prove that there is indeed order in the Universe.

for example, there might be a day when there is no more order and the universal gravitational 'constant' will fluctuate most randomly. what's to say that that's not possible? nothing. just because it has not happened before in the past and has no perceptible evidence of happening does not make it impossible to happen, because if there's anything that we can learn from the history of Scientific inquiry, it should be how right Socrates is: that we do not know anything.

so Science is built upon a single belief, that the universe is predictable (or can also be seen that there is certain order to the Universe that we can seek to understand). this belief has served humanity well. let's hope it is a reasonable belief and continue to not be proven wrong.
