Why should we celebrate the Fourth of July? Because America - as the greatest product of Western civilization - is the greatest country in the world. But it cannot remain great unless we understand the causes of its greatness.

In this age of diversity-worship, it is considered axiomatic that all cultures and countries are equal. Western culture, it is declared, is in no way superior to that of any other, not even to tribes of cannibals. To deny the equality of all cultures, claim the intellectuals, is to be guilty of the most heinous of intellectual sins: "ethnocentrism."

There are three fundamental respects in which Western culture is objectively the best. The core values and achievements of Western civilization - the values that made America great - are:

1. Reason. The Greeks were the first to identify philosophically that knowledge is gained through reason and logic as opposed to mysticism (faith, tradition, revelation, dogma). It would take two millennia, including a Dark Ages and a Renaissance, before the full implications of Greek thought would be realized. The rule of reason reached its zenith in the West in the 18th century - the Age of Enlightenment. America is the epitome of Enlightenment thought.

2. Individual rights. An indispensable achievement leading to the Enlightenment was the recognition of the concept of individual rights. John Locke demonstrated that individuals do not exist to serve governments but rather that governments exist to protect individuals. The individual, said Locke, has an inalienable right to life, liberty and the pursuit of his own happiness. This was the founding philosophy of America.

3. Science and technology. The triumph of reason and rights made possible the full development and application of science and technology and ultimately modern industrial society. Once man's mind was freed from the tyranny of religious dogma, and man's productive capacity was freed from the tyranny of state control, scientific and technological progress followed in several interdependent steps.

The result of these core achievements was an increase in freedom, wealth, health, comfort and life expectancy unprecedented in the history of the world. These Western achievements were greatest in the country where the principles of reason and rights were implemented most consistently - the United States of America.

In contrast, it was precisely in those (Third World) countries that did not embrace reason, rights and technology where people suffered (and still suffer) most from both natural and man-made disasters (famine, poverty, illness, dictatorship) and where life expectancy was (and is) lowest.

The greatness of America is not an "ethnocentric" prejudice; it is an objective fact. This assessment is based on the only proper standard for judging a culture or a society: the degree to which its core values are pro- or anti-life. Pro-life cultures acknowledge and respect man's nature as a rational being who must discover and create the conditions that his survival and happiness require.

Despite its undeniable triumphs, America is by no means secure. Its core principles are under attack from every direction - by religious zealots who want to undermine the separation of church and state and by its own intellectuals, who are denouncing reason in the name of skepticism, rights in the name of special entitlements, and progress in the name of environmentalism. The core values and achievements of the West and of America must be asserted proudly and defended to the death. Our lives depend on them.
