The History and Ethics of VivisectionThe History and Ethics of Vivisection

Rowan (1984)*Rowan (1984)*

“It is just not adequate for scientists to argue that there is a quantum difference between the moral status of humans and other animals if they are unable to give reasons for such a belief and defend their reasons in the arena of modern philosophical debate.”

* In “Of mice and men – a critical evaluation of Animal Research”

Ethics Ethics

The philosophical study of the moral value of human conduct and of the rules and principles that ought to govern it

Moral philosophy

UTILITARIANISM UTILITARIANISM

Consequentialist theory

The right action is the one which brings about the best aggregate consequences

Total benefits outweigh total suffering

DEONTOLOGY (Rights view)DEONTOLOGY (Rights view)

Value of animals not reducible to their utility relative to the interests of others

Certain beings have certain moral rights

The use of animals in research (or farming) is wrong because it violates the moral rights of the animals used.

(1975) Animal Liberation - Peter Singer

Proposed that moral consideration should transcend the species boundary to include all sentient animals. Called for reasoned intellectual debate

Peter SingerPeter Singer

'If a being suffers, there can be no moral justification for refusing to take that suffering into consideration. No matter what the nature of the being, the principle of equality requires that its suffering be counted equally with the like suffering of any other being.'

Inherent value Inherent value - Tom Regan - Tom Regan

'Animals, it is true, lack many of the abilities humans possess. They can't read, do higher maths, build a bookcase or make baba ghanoush. Neither can many humans, and yet we don't (and shouldn't) say that they therefore have less inherent value, less of a right to be treated with respect, than do others.'

Albert Schweitzer (1875-1965)Albert Schweitzer (1875-1965)

Ethics must widen the circle from the narrowest limits of the family, first to include the clan, then the tribe, then the nation and finally all mankind.'

........'By reason of the quite universal idea of participation in a common nature, it is compelled to declare the unity of mankind with all created beings.'
