I don't exactly remember, but it must be around 12-15 years ago when I first heard of the phrase "Where science ends, philosophy starts." I have appreciated the phrase a little more every time I have thought about it.
To start with, let us try to look 'way beyond' & 'deep within' and ask some questions.
We know that there is earth, then there is moon, the solar system, the milky way and so on. Our knowledge has been very well aided by science in this regard. As much as science has made progress, truth is, it all ends somewhere. Certainly not the universe, but our knowledge or interpretation of the universe, or whatever we know of it. Then we come to the question, "What is there beyond? And beyond?!"
Now let us flip the thought process and start looking within. We know that our bodies are magnificent works of Civi Engineering, Chemical Engineering, Electrical / Electronics Engineering, Mechanical Engineering and Computer Engineering put together. If you do not believe, think of the human body's drainage system, cell mechanisms, communication between different parts of body, pumps (read heart) and the neural mechanisms. We all know, by virtue of progress made by science over years what happens and how it happens. The question arises how each individual's characteristics are different in the way she / he acts or reacts. If we keep digging, we will end up at the genes; the source code of humans. We might also realise how each of these source codes are set up. But, again, the point of contention is, who keeps on writing these source codes so that each of the six billion plus individuals in this world is unique?!
Let us leave it at that and appreciate the grandeur that we are part of - Life !!
