Induction


Talking to a friend (who is perhaps the only person I know personally who is interested in this stuff) about knowledge and specifically the problem of probabilities and frequencies and also of induction (the idea that our observations is how we get knowledge and then predict the future)

 It all comes down to 1 thing really - knowledge and the process that creates knowledge which is explained by Popperian epistemology. Induction does appear to contain some knowledge and appears to be useful. However Induction is not true, not that it happens and it is false, but rather induction does not happen at all - we always have theory first and then we attribute it to induction. However, the reason induction (or what we think of as induction) contains knowledge in some instances is because it could be part of an explanatory theory. The sun rises in the east everyday and an inductive theory of that would be like - “the sun has risen in the east until now and based on that it will be rising in the east again tomorrow”.  A valid theory that makes this "induction" true would sound like “the sun rises in the east due to the direction of rotation of the earth and will continue to do so until 5 billion years from now unless some knowledge creating entity decides to change that”. Now this theory is not induction but perfectly “justifies” the induction and is true. 

So inductive results (or what we think of as inductive results) are subsets of good explanatory theories which are true for some time. All this is a mirage anyway (since induction does not happen), but this explains why someone who mistakenly thinks induction happens would do so.

Subconscious communication

We think we communicate mostly with words. But the fact if we don't know exactly how much communication or information exchange is happening on the subconscious level. We understand so little about the brain, and consciousness that this question is unequivocally unanswered - exactly how much information exchange happen on the subconscious level. I think it is far more than we think. The conscious brain is good at reasoning after the fact i.e. coming up with reasons why we think a certain way. And these reasons are not always right - they are just an attempt by the pre-frontal cortex to make sense of how we are feeling at the time. e.g. you meet someone for the first time. There is a lot of information exchange happening. Just you looking at this person, there are processes in your brain forming an idea about this person - they way he looks, the way he walks, the way he moves, the way he smells, the way he talks, his facial expressions etc. etc. there are many other non-verbal data ...

All life is problem solving

 What is happiness? Popper answered this question the best in his answer to what is the meaning of life. "All life is problem solving" Problem in the Popperian sense is not always something bad. Problem can be any unsolved thing that you are working on and the definition is not limited to science, art etc. Raising your kids well is also a problem in this sense, and so is trying to get better at dodgeball. Working on a problem is a process of knowledge creation. So in a sense, life is a process of knowledge creation. What is a good life then? what is a happy life? It is a life where the problems you are working on, the knowledge that you are creating, are interesting to YOU. This is the key here - YOU find these problems interesting and are free of coercion in choosing these problems. This is easier said than done. I wrote about it in an earlier blog post , but I believe most misery (excluding misery due to physical pain/limitations, or psychological issues that are real e.g. ...
