A history of western philosophy in 15 parts 3: Medieval Philosophy with Anthony Kenny ,
Master of Balliol College, Oxford.
For a thousand years, between the fall of the Roman empire and the Reformation, philosophy was kept alive in the west by the Roman Catholic Church.
The great philosophers of the period were such figures as St Augustine and St Thomas Aquinas. The Confessions of St Augustine is universally recognised as one of the great books of the world.

Spirits of the Forest
Narrated by Andrew Sachs Madagascar is a treasure house of weird and wonderful wildlife. In the forests live more than 20 kinds of lemur, unique primates that range in stature from the world's smallest - the tiny mouse-lemur, weighing no more than a hen's egg - to the child-sized indri with its ghostly morning songs. In the arid south, ring-tailed lemurs scent their tails for ritual stink-fights, and handsome sifakas leap through the air from one viciously-spined branch to another, somehow without gashing their hands.
Having been isolated from the African mainland for 200 million years, almost all the animals and plants have become unique to this extraordinary island. Photographed and directed by OWEN NEWMAN

Can Britain's NIGEL MANSELL upset the Brazilian one-two at the top of the drivers' championship?
The battle between PIQUET and SENNA continued in Italy two weeks ago and it seems only Mansell can interrupt it here. The Williams driver from the Isle of Man won this race a year ago and desperately needs a repeat performance if he's to catch the leaders.
