The first theme is the relationship between humans and nature. It reaches frequently our ears by the grace of a buzzword "ecology" that human beings have a dark future because modern industrial civilization has spoiled the natural environment terribly. [end of p.76] Now, here is a question. Why shoud we protect nature? What is the reason for it? Environmental ethics furnishes two different answers, conservation and preservation. And behind these two answers there are completely different ideas on nature.
Conservationists should answer the question in this way:
If they doesn't protect nature, they will face many crises in the future. They will be forced to live worse lives. In the worst case, they may become extinct. So, they must protect nature.The point is that human beings protect nature not to fall into critical condition. It is the protection of nature for humans' own sake. It is anthropocentric (or human-centered) protection.
The reason they protect nature is not for human beings. Nothing can take the place of the primeval forests which have grown for thousands years, or the network of lives in fertile nature. They must not dispose of irreplaceable and fertile nature as tools for our daily lives. They should respect wonderful nature and keep our hands off, if possible.The point is that human beings should protect nature because it is very worthy and irreplaceable in itself. In short, nature should be protected whether it has merits for human beings or not. It is the protection of nature for its own sake. It is biocentric (or life-centered) protection.
Does one who help others in trouble expect that they will help him/her in his/her trouble ? No, he/she does not.. He/She expects help by someone, not by the very person whom he/she helped, because someone will help him/her in trouble, if the custom or rule of mutual support has taken root in his/her society.We use this logic when we talk about the necessity of welfare for the aged. For example, " Create aged-friendly society now, or you will be misery when you are aged." The point is that those who are kind to others are sure to be rewarded. (In Japanese, "Nasake wa hito no tamenarazu.")
The latter, the altruistic idea of support, says in the opposite way.
We sometimes help others in trouble because we want to ease their hardship as much as possible. After the Hanshin - Awaji Earthquake*4, many young volunteers assembled there to support earthquake victims. [end of p.78] Young volunteers didn't support them in expectation of returns, but could not help doing so.If we encounter a suffering boy sitting in a crouch, we unconsciously ask him if he is all right. This is our altruistic idea of support. The essence is "feeling of pity." (In Japanese,"Sokuin no Jo"*5)
