Regardless of differing theoretical interpretations of the ethnographic data, one
conclusion emerges out of the diverse accounts of premodern societies: the organizing principle
of their worldview affirmed the universal solidarity of all beings.
ivB. From Descartes and Jansenism to the Enlightenment
The transition from the organic conception of reality to the mechanistic paradigm occurred
through various developments between the seventeenth and nineteenth centuries. French
philosophy of the seventeenth century was strongly influenced by Cartesian and Jansenist
currents. Both perspectives, one philosophical and the other theological, set the stage for a new
conceptualization of nature and culture.
vRene Descartes, whose principle of methodic doubt is
perceived as one of the most important moments in the birth of modernity, divided reality into
two fundamental substances: mind and body. According to Descartes, mind and body are exact
opposites in terms of their essences. Mind is substance endowed with consciousness but lacking
extension. In contrast, matter lacks consciousness but has extension. It is important to realize that
Cartesian philosophy was intended to demonstrate the reality of the spiritual nature of human
beings and to prove the existence and wisdom of God. Descartes’ statement “I think therefore I
am,” was intended as a proof of the independent reality of the soul which became the foundation
for his proofs of the existence of God.
However, Descartes’ philosophy unintentionally initiated a theoretical model which led
to the dominance of the mechanistic paradigm. The crucial step taken by Descartes was the
substitution of a mechanical conception of nature for the previous organic view. As we saw,
Descartes defined matter as lacking consciousness but endowed with extension.
viThis meant that
extension became the essence of matter. That is why the realm of nature was defined simply in
terms of extension. It meant that the essential properties of matter are nothing but their
mathematical quantities in terms of different dimensions. The realm of nature was thus stripped
of any spiritual, organic, conscious, living, or magical characteristics. The Pythagorean mystic
and spiritual mathematics was replaced by abstract and uniform mathematics. From then on
mathematics became the language and principle of physics and physical reality, while the realm
of nature became a uniform space subject to calculation, quantification, formalization,
operationalization, and domination. For Descartes this implied that the realm of nature should be
understood in terms of mechanical phenomena. A machine works by mechanical laws, and the
material universe is nothing but a gigantic machine. This mechanistic conception of nature was
