Living In a Rational or Irrational Universe

Throughout history, there have always been essentially two ways of thinking about the universe.  First, we live in a universe where everything plays out by a system of rational laws.  And second, there is room for events and entities that have no rational cause.  To put things in simpler terms, one can imagine the symbolic example of a set of dominos lined up back to back.  It would seem obvious that when the domino at one end is pushed over, this would cause a chain reaction, knocking all of the dominos over.  However, a person who adheres to the second way of thinking would think it plausible that knocking the domino over at the end could lead to any number of different outcomes where there would not be a chain reaction knocking all of the dominos over. 
The second way of thinking basically says that logic and rationality does not always have to exist when events occur.  Strangely enough, this has been the pretty well dominant way of thinking throughout human history.  Religion essentially relies on this.  Belief in magic and spirits is the same.  To me it seems extremely obvious that the universe should function in a rational way.  It makes no sense to me that that an event could happen without a cause.  After all, I am a biology student who hopes to become a research scientist eventually.  How could I even form my career if not for the simple assumption that future events can be reasonably predicted, based on what has been observed in the past?
            But even I have my doubts.  It is of course true that there are many phenomena that have yet to be understood by science, as well as many more that will never be understood by human rational thought.  This is due to the limits of human intelligence, and our limited reach into the universe.  However, there are certain paradoxes which do not seem as if they could be answered, even with infinite intelligence and knowledge of the universe.  The ultimate question, of course, is why anything exists at all.  But equally confounding is the question of how consciousness can exist, or how we are able to experience the universe rather than just being inanimate objects moving about like robots.  For believers in an irrational universe, these don’t necessarily need explanations, rather they just are.  This has been an easy answer to many for difficult philosophical questions throughout history.
            But I can’t settle on such a simplistic answer.  As much as these dilemmas may call into question how far one can go in considering the universe rational, my mind simply can’t conceive of the notion of effect without cause.  My resolution is simply that, though everything must have a logical explanation, it is far beyond the scope of human intelligence to ever solve all of the mysteries of the universe.  Some answers may come in a form that our minds can’t even comprehend.  Science and rational thought has their limits, and this will probably remain true no matter how intelligent we become.  Even with our most thoroughly proven theories we have today, it is impossible to know for certain whether these are truly correct or just perceived to be correct. 

With all that being said, I mean in no way to undermine the importance of science.  Though it has its limits, it is literally all we’ve got to advance ourselves in a rational universe.  Science looks for patterns and repetition in nature through which to make predictions about the true nature of things, and how things will be in the future.  And so far, throughout human history, we’ve seemed to be pretty good at making these predictions in order to advance civilization.  At some point, we’ve all got to come to accept that there are those questions that we can never and will never be able to answer.  But this shouldn’t stop us from trying to get as close to the answers as we can.
