Importance of questions What? How? Why?
how and why.
You will get an answer to the first question within a
short period of time. It is physical in nature.
You have to spend more time to answer the second
question. It is mental in nature.
Different persons may give different answers for the
third question. They reconcile their memories with their
beliefs and values. But you will never get a true answer
for it - it is philosophical in nature.
Is philosophy still relevant to the present day world?
Take for example the effect of red color on mind. Hindu Yoga books are describing it since a few thousands of years. Para-psychology books dealt with that topic in detail. But all that was brushed off as para-science, and not authentic science. Of late,modern science had to accept it.
"Color Red Increases the Speed and Strength of Reactions"
Science has answered the question "WHAT". Science has only partly answered "HOW". Has it given the answer for "WHY"?
