There is no aspect of education, not even the so-called hard sciences, which is neutral. All teaching imparts values. A value literally means something which has a price, something dear, precious or worthwhile and, therefore, something that one is ready to suffer or sacrifice for, which gives one a reason to live and, if need be, a reason to die. Values, then, bring to life the dimension of meaning.
Values provide motives.
They identify a person, give one a face, a name and character. Without values, one floats, like driftwood in swirling waters. Values are central to one's life and define the quality of that life, marking its breadth and depth. The language of the heart tells me that something is worthwhile. I am able to perceive something as of value.
