--E.F. Schumacher, economist and author (1911-1977)

(84:8.6) Let man enjoy himself; let the human race find pleasure in a thousand and one ways; let evolutionary mankind explore all forms of legitimate self-gratification, the fruits of the long upward biologic struggle. Man has well earned some of his present-day joys and pleasures. But look you well to the goal of destiny! Pleasures are indeed suicidal if they succeed in destroying property, which has become the institution of self-maintenance; and self-gratifications have indeed cost a fatal price if they bring about the collapse of marriage, the decadence of family life, and the destruction of the home—man's supreme evolutionary acquirement and civilization's only hope of survival.

(100:2.6) The goal of human self-realization should be spiritual, not material. The only realities worth striving for are divine, spiritual, and eternal. Mortal man is entitled to the enjoyment of physical pleasures and to the satisfaction of human affections; he is benefited by loyalty to human associations and temporal institutions; but these are not the eternal foundations upon which to build the immortal personality which must transcend space, vanquish time, and achieve the eternal destiny of divine perfection and finaliter service.

    Ernst Friedrich Schumacher CBE (16 August 1911 – 4 September 1977) was a German-British statistician and economist who is best known for his proposals for human-scale, decentralised and appropriate technologies. He served as Chief Economic Advisor to the British National Coal Board from 1950 to 1970, and founded the Intermediate Technology Development Group (now known as Practical Action) in 1966.
    In 1995, his 1973 book Small Is Beautiful: A Study of Economics As If People Mattered was ranked by The Times Literary Supplement as one of the 100 most influential books published since World War II. In 1977 he published A Guide for the Perplexed as a critique of materialistic scientism and as an exploration of the nature and organisation of knowledge.
