This chapter examines some metaphysical assumptions of Aristotle and Wiener that can be seen as philosophical roots of today's information and computer ethics. It briefly describes Floridi's new 'macroethics', which he calls information ethics to distinguish Floridi's 'macroethics' from the general field of information ethics that includes, for example, agent ethics, computer ethics, Internet ethics, journalism ethics, library ethics, bioengineering ethics, neurotechnology ethics, etc. In his book, Cybernetics: or Control and Communication in the Animal and the Machine, Wiener viewed animals and computerized machines as cybernetic entities. Beginning in 1950, with the publication of The Human Use of Human Beings, Wiener assumed that cybernetic machines will join humans as active participants in society. In Moor's computer ethics theory, respect for 'core values' is a central aspect of his 'just consequentialism' theory of justice, as well as his influential analysis of human privacy.
