我想可能许光伟所指的有价值的空气是洁净的对身体有益的(至少无害的)空气。之所以这么讲是因为缺少了洁净的空气我们生命的价值就不完整了。
以下是我在搜价值和使用价值之间区别时找到的理论依据:
An Introduction to the Theory of Value--on the Lines of Menger, Wieser, and Böhm-Bawerk
Second Edition – 1910
by William Smart (1853-1915)
Chapter III
The Difference Between Utility and Value
"Thus we may say that, while utility is the importance which a good possesses as generally capable of ministering to the wellbeing of a subject, Value is the importance which a good possesses as the indispensable condition of the wellbeing of a subject. Or more fully: Value is the importance which a good acquires as the recognised condition of something that makes for the wellbeing of a subject, and would not be obtainable without the good.1 It cannot be too firmly grasped then, that the relation between utility and value is quantitative, and that the same thing may or may not have value according to change of circumstances, or difference in points of view and comparison.“
...
One begins to see that the centre of value is within us. It is only by association that we transfer to goods the “value” which we obtain through the consumption of them. We attach importance to goods only as we find that our life is incomplete or impossible without them. Thus water, air, etc., being, in their totality, conditions of our life, we attach value to them as a whole, and indeed speak of them as “infinitely valuable.” But we do not attach value to any individual portion of them, because, where there is enough to allow of waste, our lives are not dependent on any individual portion."
纯属个人理解,不知有无道理,请楼主和大家指教。
