There is a principle which is a bar against all information, which cannot fail to keep a man in everlasting ignorance-that principle is contempt prior to investigation.
Some people see things that are and ask, Why? Some people dream of things that never were and ask, Why not? Some people have to go to work and don't have time for all that.
It seems evident that everything which exists in nature, is natural, no matter how simple or complicated a phenomenon it is; and on no occasion can the so-called 'supernatural' be anything else than a completely natural law, though it may, at the moment, be above and beyond the present understanding.
The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task, it has a rudimentary nervous system. When it finds its spot and takes root, it doesn't need its brain anymore so it eats it!

It is what you were a second ago that is the “I” of the “me.” It is another “me” that has to take that rôle. You cannot get the immediate response of the “I” in the process.
Entities of an essentially new sort are entering the sphere of scientific thought. Classical science in its diverse disciplines, be it chemistry, biology, psychology or the social sciences, tried to isolate the elements of the observed universe - chemical compounds and enzymes, cells, elementary sensations, freely competing individuals, what not -- expecting that, by putting them together again, conceptually or experimentally, the whole or system - cell, mind, society - would result and be intelligible. Now we have learned that for an understanding not only the elements but their interrelations as well are required...
