Why to gain knowledge?
We have not yet answered the question in the title. Have we? We will soon!
Lets us consider an example. Two animals are walking down a path. One of them falls into a quick sand, what would another animal do? We cannot say anything deterministically, however lets assume that the animal wants to help other animal with all its capability. It still cannot, because it doesn’t have enough knowledge to help the other animal. Lets us consider a different scenario, Earth and Mars are orbiting around Sun and an asteroid is in the orbit of Mars. Can Mars save itself from the danger? Probably no. But if somehow Mars could signal Earth that it needs help, collective knowledge of all the people in the earth can pitch in and help. Thus,
“Service that we can offer to others is a function of Knowledge that we possess.”
