As we approach the twenty-first century, mankind has been able to overcome most physical disease, sent men to the moon, and even created the cloned creature Dolly. There are also many other examples I could give of the fruits of science and information technology (IT). On the other hand, mental disease, local wars, and problems of senility remain unsolved. These kinds of things cannot be solved by science because they belong to the “actuality” we live in between birth and death, in which we fundamentally cannot know what will happen in the next moment. It is the law of living things that we have to make decisions about the future without being able to determine the results of those decisions in advance. Science can be applied only to well-defined problems whose results can be known or at least anticipated beforehand. Science provides the means to control nature as reality, but cannot control living things as actuality.
