The Four Qualities of Life

The terms 'quality-of-life', 'well-being' and 'happiness' denote different meanings; sometimes they are used as an umbrella term for all of value, and at other times to denote special merits. This paper is about the specific meanings of the terms. It proposes a classification based on two bi-partitions; between life 'chances' and life 'results', and between 'outer' and 'inner' qualities. Together these dichotomies imply four qualities of life: 1) livability of the environment, 2) life-ability of the individual, 3) external utility of life and 4) inner appreciation of life.
