Philippa Ruth Foot (née Bosanquet; 3 October 1920 – 3 October 2010) was a British philosopher, most notable for her works in ethics. She was one of the founders of contemporary virtue ethics. Her later career marked a significant change in view from her work in the 1950s and 1960s, and may be seen as an attempt to modernize Aristotelian ethical theory, to show that it is adaptable to a contemporary world view, and thus, that it could compete with such popular theories as modern deontological and utilitarian ethics. Some of her work was crucial in the re-emergence of normative ethics within analytic philosophy, especially her critique of consequentialism. A familiar example is the continuing discussion of an example of hers referred to as the trolley problem. Foot's approach was influenced by the later work of Wittgenstein, although she rarely dealt explicitly with materials treated by him.

Foot's works of the late 1950s were meta-ethical in character: that is, they pertained to the status of moral judgment and speech. The essays Moral Arguments and Moral Beliefs, in particular, were crucial in overturning the rule of non-cognitivism in analytic approaches to ethical theory in the preceding decades.

Philippa Forrester (born 20 September 1968 in Winchester, Hampshire) is an English television and radio presenter, producer and author. Having presented shows such as Tomorrow's World, The Heaven and Earth Show and Robot Wars, she now makes wildlife programmes with her husband, Charlie Hamilton James.

Forrester was educated at Westgate School, a co-educational comprehensive school in Winchester, Hampshire, and at Peter Symond's College in the same city. She holds a degree in English from the University of Birmingham, where she appeared on the internal Students Guild television station.

Forrester first worked as a children's presenter for BFBS television in 1986, and was often seen reading out birthday cards onscreen. She became a presenter on Children's BBC from the late 1980s, becoming a more regular fixture alongside Toby Anstis from July 1990 until 1994. She then went on to host many programmes including Tomorrow's World, Barking Mad, The Heaven and Earth Show and Robot Wars.

She also co-presented the BBC's coverage of the solar eclipse of August 1999. At the end of the same year she was also part of the corporation's team covering the turn of the new Millennium, and was duped into appearing on the spoof documentary Brass Eye's notorious 2001 paedophilia special, in which she wore a large pair of gloves, and explained how a paedophile could use them to touch children through a screen, such as a television screen.
