All conservative viewpoints are reactions to liberalism. The conservative viewpoint, whose ethic supposedly eschews dogma and doctrine, can be traced back to the work of Edmund Burke who, in Reflections, published in 1790, outlined his understanding of the fallacies of the French Revolution.
Burke attempted to make it clear that while a social contract did exist between the governed and the government as the revolutionaries asserted, each state’s “contract” with its people is but a smaller part – a clause as Burke put it – “in the great primeval contract of eternal society.”
Burke established the basic themes of conservatism that have remained as subtext for all later debates: that underlying all human systems is a deeper moral structure that is eternal and transcendent. The struggle for conservatives is to preserve or “conserve” the relationship between human systems and that moral structure, to protect it from the onslaught of the “liberal” who seeks to change things. For the liberal, the "moral structure" must have compelling reason to outweigh and overrule the essential liberties of human beings. .
Traditions, policies, hierarchies, routes of power and chains of command are all or variously seen by the conservative as root connections to the transcendent moral structure. In essence the heart of conservatism is the idea that we must hold on (or return) to that which defined us and brought us to where we are. Those things are our connections to what gives our society meaning and provide a path along which to make choices.
“Society is not held together by abstract principles such as a ‘social contract’,” Burke said, “but by people bound together through a sense of history, shared experiences and common beliefs.” All of the rhetoric aside, Burke’s premise remains at the core of the conservative ideology, such as it is.
While there is no more likelihood of locating a specific and unifying dogma for liberalism than there is for conservatism, liberalism like conservatism, has its roots in intellectual movements of previous ages.
Liberalism is based on two ideals:a defining sense that the dynamic relationship between the good of the society and the needs and desires of the individual must be balanced in a way that conveys a strong respect for individual liberty and an openness to change and progress which arises from the tendency for the liberty of the indvidual to be seeking new frontiers.
Much of what is now considered “liberal” thought derives from the work of John Locke and Jean-Jacques Rousseau who expanded early definitions of natural law into an affirmative assertion of individual freedom vis-à-vis autocratic or societal domination. Rousseau in particular asserted that the individual’s compliance with society was self imposed due to an understanding of the concepts of the greater good and from the citizen’s natural desire to be a member of society. Inherent compliance is a “social contract” that empowers a government whose primary function is to bring about an articulation of the will of a of people.
In short, the functions of a government are ceded to it by a people in order to assure the general welfare of their community or society. From Rousseau derived the concept of popular sovereignty and with it the idea that a people are self-determining and that government is a tool for that self determination.
What tweaks conservatives is the liberals’ support for the idea of individual liberty, which Roger Scruton called the “great social artifact.” Scruton delineates the essence of the controversy: “One major difference between conservatism and liberalism consists, therefore, in the fact that, for the conservative, the value of individual liberty is not absolute, but stands subject to another and higher value, the authority of established government.”
Much philosophical and political rhetoric has flowed over the dialectical dam since the 18th century and positions on issues have hardened, softened, reformed and dissolved. When Burke and Rousseau were writing the forms of government in Western Europe consisted of monarchy and constitutional monarchy, with the budding concept of the democratic republic. Since then a much greater political diversity has emerged so that governments can be variously monarchies, constitutional monarchies, democratic republics, socialist democracies, communist dictatorships, totalitarian autocracies, and fundamentalist theocracies to name but a few of the possible permutations. As nations have been established and wars fought amongst these governments the dialog between liberal and conservative has taken on greater weight.
