“Why?” is not the ideal question to ask if you want to get closer to the nature of things; “How” would provide more hints than “Why”. The renunciation of the classical ideal of causality didn’t come from some fluffy post-modernism theories, but from hard-core science of quantum mechanics. According to Heisenberg’s Uncertain Principle, it’s impossible to determine simultaneously both the position and velocity of an electron or any other particle with any great degree of accuracy or certainty.
Where do moral sentiments originate? Perhaps we’re really only “a bundle of sensations” that Hume described? Sentimentalists say ethics is based on (gut) feelings rather than absolute moral principles. It may sound wacky but feels closer to the answer. Reason cannot be behind morality. One cannot be motivated by reason alone; it got to involve the input of the passions.
Philosophy can be defined as the human desire for the fundamental explanation that is never met. It is the constant attempt to understand a reality when we know we can never get beyond our limited consciousness. Therefore we are locked in a process of continuously philosophising in a futile attempt to deify our place within reality.
A miracle is a violation of all prior experiences.
