When the number of factors coming into play in a phenomenological complex is too large scientific method in most cases fails. One need only think of the weather, in which case the prediction even for a few days ahead is impossible. Nevertheless, no one doubts that we are confronted with a causal connection whose causal components are in the main known to us. Occurrences in this domain are beyond the reach of exact prediction because of the variety of factors in operation, not because of any lack of order in nature.
Albert EinsteinThe word 'God' is for me nothing more than the expression and product of human weaknesses, and religious scripture a collection of honourable, but still primitive legends which are nevertheless pretty childish. No interpretation, no matter how subtle, can (for me) change this.
Albert EinsteinNo, this trick won't work... How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love?
