Clark concludes the series with his discussion of materialism and humanitarianism of the past century. This takes us from the industrial landscape of nineteenth century England to the skyscrapers of twentieth century New York. The achievements of the engineers and scientists - such as Brunel and Rutherford - having been matched by the great reformers like Wilberforce and Shaftsbury.

Here Clark argues that the French Revolution led to the dictatorship of Napoleon and the dreary bureaucracies of the nineteenth century and traces the disillusionment of the Romanticism artists is traced from Beethoven's, Byron's poetry, Delacroix's paintings to Rodin's sculpture.

Belief in the divinity of nature, Clark argues, usurped Christianity's position as the chief creative force in Western civilisation and ushered in the Romantic movement. Here Clark visits Tintern Abbey, the Alps, and there discusses the landscapes of Turner and Constable.

Here Clark discusses the Age of Enlightenment tracing it from the polite conversations in the elegant Parisian salons of eighteenth-century, through the subsequent revolutionary politics to the great European palaces of Blenheim and Versailles finally to Jefferson's Monticello.

Here Clark talks of the harmonious flow and complex symmetries of the works of Bach, Handel, Haydn and Mozart — and the reflection of these in the Rococo churches and palaces of Bavaria.

Here Clark tells of new worlds in space and in a drop of water that the telescope and microscope revealed, and the new realism in the Dutch paintings which took the observation of human character to a higher stage of development.

Again in Rome of Michelangelo and Bernini, Clark tells of the Catholic Church's fight against the Protestant north, the Counter-Reformation and the Church's new splendour symbolized by the glory of St. Peter's.

Here Clark takes us back to the Reformation. That is to the Germany of Albrecht Duerer and Martin Luther, the world of the humanitarians Erasmus, Montaigne, and Shakespeare.
