But if we accept the notion that nothing can ever be known with certainty, can we even talk abut determinism? If we are never sure we get mysticism and I don't believe in mysticism. I do accept the notion of "probabilities" of natural occurrences. But only when there is a probability of 100% can it be called deterministically true, no? How do we know a probability is ever 100%? If this is always subject to correction can we even talk about determinism?
