French materialism combined the associationist psychology and Empiricism of John Locke with the Totality of Isaac Newton to create a complex world view in diametrical opposition to the Cartesian dualist world view.
La Mettrie inputs
With Man a Machine
, La Mettrie opposed Descartes
on all fronts and asserted a combination of the mechanics of a single substance and matter in motion from Spinoza
and Isaac Newton, with self love as the prevailing law and the quantitative difference that separates man from animal.
He agreed with the idea of Locke that humans form ideas from associating sensations and believed that we could grasp our own cognition but that we did not know how we grasped it.
To La Mettrie, the body controlled the mind - a mere effect of the body's working. La Mettrie's teleology
postulated that the world has a reason for being and is going for some unknown goal and that man exists simply to exist without knowing the real reason.
However, La Mettrie left many questions unanswered.
introduced a higher rationality
by which our competitive nature works for the higher good of society
. He stated that the hidden hand of nature gave it a moral purpose, while our narrow view creates the war of all against all (Bellum omnium contra omnes
). His idea of progress as the key to a better world was not to create something new, but to eliminate the errors of our world. Helvetius created his Rational Ethics
(later dubbed Utilitarianism
) which stated that there are only two motives: pleasure and pain. He postulated a society where self-love pushes us to maximize pleasure and minimize pain. He stressed that this society should only exist on the basis of the greatest good for the greatest number, this being best achieved by universal education and an enlightened legislation.
's dynamic nature told him that things do not just change; things change for the better. This novelist, art critic and editor of the most famous product of the Enlightenment
, The Great Encyclopedia
, saw nature as a totality of creative changes. Each of these changes reverberates through all of nature to maintain a constant newness. This view agreed with Diderot's idea of progress that concurred with Helvetius elimination of errors, but proposed that we should also expand and create new institutions. Diderot's psychology
differed slightly from Lockes
as he saw the mind as active, forming general ideas then using those ideas to create more knowledge and ideas.
Baron d'Holbach notions
The Baron d'Holbach's System of Nature
applied the Mechanistic Materialism
to the whole of nature and proposed that consciousness
has the ability to produce a new order of reality broken down into three subsets; brute facts, social facts, and mental facts. d'Holbach thought it to be human nature to understand the world and act upon that understanding, such actions satisfied d'Holbach's notion of progress.
Marquis de Condorcet expressions
The Marquis de Condorcet's Sketch of Intellectual Progress
popularized progress as a natural law and sketched the key to such progress to be the advancement of science
and its application to government
and social order
. The first philosophe to call for gender equity
, Condorcet also stated that history
was moving towards a goal which would be the outcome of the application of reason
, a sort of scientific utopia
The Physiocrats model
Finally, the Physiocrats seemed to set the class boundaries with their model of the French economy
. To them, the problems of the economy
lay within the parasitic, landowning aristocracy
that seemed to serve no function but to hold the land. They thought the source of wealth flowed from the productive class, made up by the peasants, which they stated should be allowed to operate unhampered. The manufacturing class supported society with their goods. The Physiocrats
coined the term LaissezFaire meaning to allow the economy
to operate according to its own laws without alterations. They also first used capitalist
, as they wanted to transform the countryside from the seigneurial
to the entrepreneurial
