Absolute ethics
An ethical theory such as Kantianism which argues that x should always be done, regardless of circumstance
Act Utilitarianism
Argues that one should always perform that individual act which will lead to the greatest balance of good over evil. Main supporter Jeremy Bentham
A Posteriori
That which can be known to be true only through sense experience. E.g ‘There is a cat in that room.’ Can only be determined to be true by observation, directly or indirectly.
A Priori
That which is knowable without reference to sense experience . The truth of ‘2+2=4’ follows from the definition of the terms, not from knowledge of things in the world. It does not mean innate.
Categorical Imperative
Kant’s guide to duty which is morally obligatory, hence categorical. Q.v. Principle of Universalisation
Cognitive Language
Language about which it is appropriate to ask whether it is true or false. ‘Cognitive’ is not a synonym for true. E.g ‘Paris is the capital of Vietnam’ is cognitive but false.
Conscience
The faculty said to enable us to make moral decisions and to judge our own and the actions of others. Some have described it as the voice of God, or otherwise innate, but for Aquinus it is a species of practical reason.
Deontological Ethics
Any ethical theory which argues that the rightness if an act lies in doing the right thing because it is the right thing in itself, regardless of any consequences.
Determinism
Any theory which holds that events are the direct effects of previous causes without intervention of free choice
Emotivism
The theory advanced principally by Logical Positivists that ethical sentences merely evince emotions and cannot be justified. Named the ‘Killing-boo’ theory by Winston Barnes. The emotion need not be felt by the one making the statement.
Ethical Naturalism
A meta-ethical theory which holds that ‘good’ is a synonym for a purely natural quality, such as pleasure.
Ethics of duty
The belief that right living means always performing one’s rationally determined duty. The term is often used to describe Kantian ethics.
Eudaimonia
There is no exact translation of the Greek term, the goal of Aristotle’s virtue ethics. It is commonly translated as ‘flourishing’ or ‘happiness’ and has elements of both.
Falsification
Devised by Karl Popper as a criterion of demarcation between the scientific and non scientific. It argues that science advances by proving theories false and devising better ones.
Hedonic Calculus
Bentham’s attempt to construct a system which would determine, on strict utilitarian principles, precisely the right action to take in any circumstance that may arise. The experiment failed.
Hypothetical Imperative
Kant contrasts this with the Categorical Imperative. The latter is obligatory, the hypothetical is not. E.g if I wish to go to university, there are steps I must take, but there is no obligation to go to university.
Intuitionism
The ethical theory, associated with G.E Moore, that one simply intuits the good, it is a category of mind.
Meta Ethics
Considers the meaning and justification of ethics. Normative Ethivs (q.v.) attempts to show we should live, while meta ethics considers the meaning of terms such as ‘good’ and ‘right’.
Moral responsibility
The idea that people are responsible for their own actions, except in cases of immaturity or mental illness etc, and thus are open to blame.
Natural Law
‘Right reason in accordance with nature.’ This believes that by reason alone we can determine Whig actions are good or bad for human flourishing.
Negative Utilitarianism
Instead of seeking to maximise pleasure, this seeks to minimise suffering. Peter Singer is a major advocate.
Non Cognitive Language
Language about which it is inappropriate to ask whether it is true or false. E.g, prayers, curses, poetry
Normative Ethics
Ethical theories which inform people how they should act.
Phenomenon
That which is presented to us in sense experience. Kant, the most significant Phenominalist, argues that we can never know the world as it is, only as it is presented to us in a sense experience.
