“In the eighteenth century, the Scottish Enlightenment focused attention on Glasgow and Edinburgh as centres of intellectual activity. The Scottish Enlightenment was an intellectual movement which originated in Glasgow in the early eighteenth century, and flourished in Edinburgh in the second half of the century. Its thinking was based on philosophical enquiry and its practical applications for the benefit of society ('improvement' was a favoured term). The Enlightenment encompassed literature, philosophy, science, education, and even geology. One of its lasting results was the founding of the Encyclopaedia Britannica (1768-71). The effects of the Scottish Enlightenment, especially in the second half of the century, were far-reaching in Britain and Europe.The philosophical trends ranged from the 'common-sense' approach of Thomas Reid to the immensely influential works of David Hume, notably his Treatise of Human Nature, published in 1739. Here, his arguments on God, and the cause and effect of man's relationship with God, are far ahead of their time in the philosophical debate in Britain: .......Adam Smith's book The Wealth of Nations (1776) was probably the most important work on economics of the century, revolutionising concepts of trade and prophesying the growing importance of America as 'one of the foremost nations of the world'. By a remarkable coincidence, the book was published in the very same year as the American Declaration of Independence.”

“In the eighteenth century, with the growth of publishing and with the intellectual climate of the Enlightenment, there was a great demand for new historical writing. The greatest product of this was The Decline and Fall of the Roman Empire, a massive six-volume work published between 1776 and 1788, precisely between the American Revolution and the French Revolution. The context is important, as the author Edward Gibbon was examining not only the greatness of Rome, but the forces which brought about its decay.......Gibbon's interpretation of history was controversial, especially in its examination of the growth of Christianity, but his accurate scholarship and engaging prose style have made The Decline and Fall the most enduring work of history in English.In the eighteenth century, history is seen as a branch of belles-lettres, and it subsumes within it scriptural authority on the one hand, and fictional narrative on the other. History is, in effect, the new secular authority of the Enlightenment, and comes to be a very wide-ranging category of writing.”

“In the eighteenth century, philosophers considered the whole of human knowledge, including science, to be their field and discussed questions such as: Did the universe have a beginning? However, in the nineteenth and twentieth centuries, science became too technical and mathematical for the philosophers, or anyone else except a few specialists. Philosophers reduced the scope of their inquiries so much that Wittgenstein, the most famous philosopher of this century, said, "The sole remaining task for philosophy is the analysis of language." What a comedown from the great tradition of philosophy from Aristotle to Kant!”

“Revolution was the great nightmare of eighteenth-century British society, and when first the American Revolution of 1776, then the French Revolution of 1789 overturned the accepted order, the United Kingdom exercised all its power so that revolution would not damage its own hardwon security and growing prosperity. Eighteenth-century writing is full of pride in England as the land of liberty (far ahead of France, the great rival, in political maturity), and saw a corresponding growth in national self-confidence accompanying the expansion of empire.”

“Israel's monomaniacal Spinoza worship is amusing and exasperating by turns. For a start, his insistence that Spinoza was the singular font of the Enlightenment leaves him without a story of the Enlightenment's intellectual or cultural origins. Every historian has to begin somewhere, but the fact that Israel begins with Spinoza, and then reduces most of what follows the philosopher to a footnote, leaves his account of the Enlightenment founded on something like immaculate conception.”

“Every man of ambition has to fight his century with its own weapons. What this century worships is wealth. The God of this century is wealth. To succeed one must have wealth. At all costs one must have wealth.”
