Science is vitally important when it is harnessed to reveal the law of human life.
In order to accept the importance science, we must prove that this activity is useful. Scientists usually demonstrate that they are doing something and that maybe sometime, someday, this could be useful for people in the future.
The universe is limitless, and impossible for anyone to understand. Therefore, we cannot completely understand the life of our own body.
— Blaise Pascal
"Science" is not quite the concept which people use this word to identify; it is the highest, most important most necessary object of our understanding.
