In accordance to this philosphical tradtion, a medical ethicist, viewing a situation through absolute truth, would have to tailor his point of view through immutable truths, such as the sanctity of life. .
A situational ethicist, viewing the world through sensibility would argue that the general principles for viewing ethical points of view are grounded in human experience and the only absolute truth is change itself. A. J. Ayres, the philosphical father of situational ethics, would argue that the criteria for an ethical course of action are logic, validity of data, and the consequnces. ". We have to know what the situation is in which we are likely to be. If, for example, we think it right to try to maximize human happiness, a scientific approach to the practical problems may instruct us how best to set about it."(A. J. Ayres The Central Quenstions of Philosophy pp. 226). Unlike the believers in catholic truth, A. J. Ayre does not believe that their exists only one moral stand-point which is superior to all others. ".In the end, it is a matter of finding principles which one is prepared to stand by and when they conflict. of giving more weight to one or the another acco!.
rding to the circumstances of the particular case."(A. J. Ayres The Central Questions of Philosophy pp 266) However, this does not mean that all moral standpoints are to regarded as equal to one another. ". one can argue ad hominem. One may be able to show that their principles are based on factual assumptions which are false, or that they are the product of bad reasoning, or that they lead to consequences which their advocates are not prepared to stand by."(Ayres pp 227). So, all ethical perspectives which are logicall y consistent should not necessarily be treated as equal to each other. In viewing the ethical point of view, no reference frame can be proven to have a preferred bias to any other reference frame provided that the reference frame is self consistent (lacking inconsistancies).
