Then as the caravan proceeded, it got split into two groups with two different sort of approach to life and natural phenomena. The logical offshoot is what we today know as science while the intuitional offshoot is today's philosophy.
Even in science, its branching happened much later. The main aim of science is to understand the reasoning behind the phenomena occuring in nature and use the principles of nature in devising different instruments for our comfort. Initial scientists were of the inter-disciplinary kind. For e.g. Robert hook, he has important contributions in the field of biology as well as physics. Other biologists also had an understanding of optics and hence could refine the quality of microscopes with passing time. Best example of chemist-physicists are Michael Faraday and Leonard Jones.
Then again, as the caravan proceeded, science also got split into three main pure science branches viz. chemistry, biology and physics.
But chemistry and biology are bounded fields and quite different from primitive philosophy. While physics remains unbounded and tries to explain all the phenomena occuring in nature. And it is the only pure science field which has a common boundary with philosophy. And if this boundary is transformed into a fine gradient, mankind will understand " The Philosophy of Life " logically.
This gradient may be achieved from both the ends. Along with advancement in physics and its concepts about the fundamental forces, there has been great refinement in our views of God and Life. Today, we have amongst us, theories such as theories such as Spinoza and Gaia which are enough to force one into contemplation.
Finally,I'll quote my ideal:
“The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when one contemplates the mysteries of eternity... Never lose a holy curiosity.”
"I believe in Spinoza's God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with the fates and actions of human beings."
- Albert Einstein.
For an ending remark i'll like to say that in the past, science had seperated from philosophy and now, its time for their eternal re-union.
