Determinism and Causality

Its time to look at some of questions which perplex me the most which are -> " why are we there here in the first place ? " , "Is there any purpose for human existence ? " , " Are there any reasons or answers for this ?"," Is it reasonable for everything to have reason ?", Why am I searching for reasons for everything ? It seems that we are locked or bound by the law of causality which is why we keep searching a cause for every effect. This is a possibly endless chain which starts from an axiom. The axiom is the only statement or truth we accept without any cause. So it seems that organic-carbon based logic is constrained by the cause and effect principles. The question is whether everything can explained by such logic , now this statement is ridiculous as "explain everything" inherently means finding the cause for a perceived universal set of effects. Is this thinking attributed to carbon based organic thinking , What if had a silicon based brain , would I still be constrained by causality ?

Coming back to axioms it seems that human beings are surprisingly different in the set of axioms they start off with. There are these religious people (the worst of the lot) who have a zillion axioms which begin with the concept of god, then we have the mathematical/rational people who accept only the most atomic truths as axioms. Yet the rational man as well as the religious one has to accept that inbuilt in our brains is the notion of survival , ultimately a man only strives to maximize those objects that increase the chance of his survival and this unfortunately has been programmed into us through the complex and chronologically gigantic process of evolution.

Now there arise interesting questions regarding rationality and human behavior. Its often seen that we criticize a person accusing him of taking incorrect decisions during a bout of emotional outburst. We tend to classify human behavior as rational or irrational as to whether the person's current action leads to a perceived increase of objects that lead to a greater survival probability (for example increasing his financial stability -> and note that concepts like finance , jobs etc are abstractions of basic objects needed for survival). Now looking deeply into this we find something quite funny. Was the person who took the so called "emotional" decision really in control ?. Lets define the state of the human brain in terms of a finite number of variables or parameters (most of these parameters would probably be electric potential values and chemical states of the brain). Now given a particular state of the brain (which is supposedly an emotional state) and the input stimuli to the brain it can be possibly predicted as to what the next state of the brain is. Thus the action taken by the person was not in "his" control but was predetermined. Now arises the bigger question -> does there exist anything called free will ? I will quote my friend's magnificent quotation here -> "Free will is merely the result of the computational complexity of determinism" .. yes given the millions of possible states and multitude of stimuli the problem is hard.

On a more observatory note (and assuming that people do have free wills) I feel amused on looking at the lives of so many people who wade through life , it makes me think that a majority of us are overgrown and biologically complicated ants running along dabbling in trivial things for survival or its extensions. I really appreciate people who strive to push the boundaries of thinking , reasoning or logic in any field from Computer Science, Neural Research to philosophy . Only an advancement in human thinking can be considered as a non trivial achievement (if at all there exists a notion of non triviality for triviality is relative) .. the rest of human actions are repetitive, predictable and boring.

No Title

Just set up this page and hopefully will start writing something here .. an interesting question arises immediately --> why do I wish to do this ... what is the need to write, what purpose is it serving .... how come humans have evolved so many abstractions. Communication in animals is purposeful and related to survival and we have evolved such complex networks of purposeless(?) interaction. Are we really successful as a species ... after all the aim of any species is to maximize its survival and dominate "nature" ... so how does one define domination ? Is our success and domination measured by our numbers ? I think it is .. our success as a species is commendable .. we have taken over this planet. What puzzles me is the fact that in order to be so successful we have had to develop so many complex abstractions while a simple virus does the same with much less complexity .... of course triviality and complexity are subjective issues and are hard to define.

So I join other members of my species and to try and broadcast some of my thoughts. Before signing off I ask a question that frustrates me --> Why is existence not like a computer program .. If I want to change the working of some program, I reverse engineer it ... wish I can do that with life.
