How to protect the value of human embryo

My personal view is that a stronger argument is needed for protecting the value of the human embryo, including a cloned human embryo, especially in Japan where the “language of religion” has little clout in the discussion. Instead of religious language, we need “philosophical language” to affirm the value of a human embryo or “the sprout of human life.”

What is it we wish to protect when we use the word “the sprout of human life”? The answer would be “a vigorous energy to develop and transform itself” that we once were, that we came from, and that we still have at the basis of our existence. This is what we have to protect, even if its destruction would be beneficial to the progress of medicine. Why then should we protect it? The answer would be that its destruction means the destruction of something very important which we actually “share” at the basis of our lives; hence, its destruction might lead to the destruction of ourselves. The ultimate danger of research on human embryo is that in the long run it might erode something very important inside us in the name of social welfare and the progress of medicine. We need “philosophical language” to explain the core meaning of the words “something very important” in a way that can be easily understood by the general public. In this sense, we need a new “philosophy of life,” or “life studies,”(15) which will give us the wisdom to protect “something very important” from our own selfish desire to live a long and healthy life.
