Holistic comes from whole and also holy and means that something includes both the qualitative and the quantitative, seen and unseen, physical and metaphysical aspects. Our culture is a bit lopsided because it has favored the quantitative aspect of science over the spiritual aspect at least since Isaac Newton. But the qualitative aspect, the spiritual, the unseen, is what adds the yummy factor to life. Knowledge of the calories of a strawberry, or its vitamin content, is pretty dull and meaningless without the smell of the ripe fruit, the visual appreciation of its red ripeness, the feeling of the teeth sinking into the juicy flesh, and finally that distinct sweet strawberry taste on the tongue.
The yummy factor is what makes life worth living.
