N.B.: The much broader writing of mine that discusses the sources of morality, entitled Sciences and Values, is available here. Read it through carefully!
Human beings first appeared on Earth 400.000 years ago,/1/ much older than the birth of the oldest religion so far as science can show. According to the latest archaeological findings, the oldest religion was constructed 70.000 years ago among Basarwa people in Botswana, Ngamiland, South Africa./2/
However, you should first remember that moral values exist not in heaven you are going to apply after death, but in this world, in the realities of our daily lives, and are therefore part of natural realities explorable and analysable by sciences.
A good and kind man is not only a moral or ethical man, but also a real man, a factual man, in short a fact that is explorable, explainable, analysable and distinguishable by science. A bad and evil man is not only an immoral man, but also a real man, a factual man, in short a fact that is explorable, explainable, analysable and distinguishable by science too. Scientists, therefore, know what you exactly mean by a good and kind man and by a bad and evil man respectively. These two types of men are distinguishable by science, both social science and neurobiological science. Consequently, science does concern with moral values embedded in any facts it explores, explains, analyses, and distinguishes.
Another example will suffice. Suppose you have a tumor growing steadily in your brain. As scientists, your physicians know well not only about your growing tumor as a fact in your brain that makes you feel a terrible pain every day in your head; they know well too the consequences that will arise from the tumor to your behavior and personality. Very likely, the tumor will change your mental, making you gradually either a temperamental people or, at last, a psychopath. This final condition of your mental health is not only a psychological or biological problem, but also a value problem of your remaining life. Knowing that this condition is bad not only for your biology but also for your meaning of life, your physicians of course will try hard to cure you by removing the tumor from your brain with great care. The surgery and the meaning of your remaining life interact.
Do not forget that sciences that you have make you an intelligent and smart human being. Being intelligent and smart is a value, a priceless value, that sciences give to you.
It is clear then that science has many things to do with moral values.
As the conclusion of this piece of writing, this saying of His Holiness the Dalai Lama is worth pondering: “We can teach people how to be happy on the basis of secular ethics, that a compassionate mind is useful, beneficial and secular in nature.”
