Philosophical Thought About Life Sciences Technology

In the 20th century, especially in the late of it, life sciences technology has developed by leaps and bounds. From artificial fertilization to heart transplant, from gene testing to gene engineering , to Cloned man appearing at any moment ,human controlling of advanced and developed technology swiftly is digging into the core of human being something done impossibly in the past has been possible now ,is it good future or bad future ,is it to exist or destroy ? So it has challenged traditional ethnics. Namely it has put forward to what should be done and what should not be done and how to be done .So philosophical thought about life sciences technology has been put forward to .The thesis aims to probe into humanity confliction by life sciences technology and concludes what can be done is not what should be done . It is the key point of this thesis from which the author bring forward philosophical thought about life sciences technology. The thesis analyses humanity conflictions by life sciences technology from the point of humanity. So we should master ethnical bottom. The thesis is divided into three parts except preface.In the first part, the thesis discusses anthropological essence on life sciences technology, it is a kind of activity of knowledge and transformation on nature essence of human from the point of anthropology, nature essence of human is life activity, life science technology is knowledge on essence and law of life, it also a improvement and recombination and optimization on life, it makes nature activity of human possesses a character beyond nature, this is intensification and leap in the process of cognitionand transformation on nature--in the past activity by which nature is conformed ,life change is passive, such as shape change of life, but when human remakes their nature by use of life sciences technology, change of life activity has become active. Namely human improve on life process on according with their wishes.In the second part, the thesis analyses humanity conflictions in detail. It is the emphasis of the thesis. The first confliction is between naturalness and sociality. Life sciences technology changes naturalness of human, but human is social, so confliction is appearing, for example, sex selection belongs to naturalness, human can select sex in the basis of life sciences technology, but sex has a series of social qualities, such asequality of man and woman, marriage and etc, so sex selection produces some social contradictions; The second confliction is between individuality and humanity. Individuality means selfishness, ego centricity, but humanity means selfless, self-sacrificing, cooperation, mutual aid. Life sciences technology can copy and continue human life, but resource is limited, so the problems of resource distribution are appearing; The third confliction is between instrument reason and value reason, instrument reason concerns "what we can do", value reason concerns "what we should do", confliction between what can be done and what should not be done produces in the process of transformation on human life by use of life sciences technology, the confliction between instrument reason and value reason is becoming acute in the life sciences technology ,it makes us turn over to think the two kinds of reasons in the spirit field profoundly.The third part is conclusion, "what we can do" is not "what we should do", so we should control ethnical bottom. Firstly the thesis interprets the production of life ethnics, it is the result of humanity conflictions, it provides ethnical bottom for life sciences technology, namely life sciences technology should be limited in the bound of humanity; It also introduces the definition and rise of life ethnics; Finally the thesis obtains absoluteness and relativity problem of ethnical bottom, absoluteness means life sciences technology must be controlled by value reason, it is absolute, it is rooted in the aim of human activity, the aim is better existence and development of human being, relativity means something that can not...
