Fletcher's Four Working Principles (also called presuppositions) are foundational assumptions you must accept before applying Situation Ethics. They are: (1) Pragmatism—the most loving action must actually work in practice, not just in theory; (2) Relativism—there are no absolute rules except love itself; what's right is relative to the situation; (3) Positivism—you must accept on faith that agape love is the supreme value; it can't be proved by reason; (4) Personalism—people come before rules; ethics is about human relationships, not abstract laws. Remember them as "the three P's and an R": Pragmatism, Positivism, Personalism, Relativism. These principles set up the framework; the Six Propositions then explain how love actually operates within that framework.
"The heart of this explanation of situation ethics lies in its six propositions… But there are a few preliminary matters to be made plain first, in the reader's interest, so he can know what presuppositions are at work."
"The good, like the true, is whatever works." — Fletcher
"Philosophy is utterly useless as a way to bridge the gap between doubt and faith."
Fletcher uses "pragmatism" in a simple, everyday sense—not the complex philosophical theory of Dewey, Peirce, and James. He simply means: be practical, focus on what works.
"As the strategy is pragmatic, the tactics are relativistic." — Fletcher
Fletcher "relativizes the absolute" but "does not absolutize the relative".
What This Means:
Only moral claims valid when relative to love will be justified.
"Any moral or value judgment in ethics, like a theologian's faith propositions, is a decision—not a conclusion. It is a choice, not a result reached by force of logic." — Fletcher
Fletcher's "positivism" is NOT the same as logical positivism (Ayer's verification principle). He uses the word in a different, simpler sense: positively choosing to accept a value.
When challenged: "How can you justify that the only law is to maximize love?" Fletcher answers: "I cannot prove it logically. It is a decision, a choice, like faith."
"Love is of people, by people, and for people. Things are to be used; people are to be loved." — Fletcher
"The Sabbath was made for man, not man for the Sabbath." (Mark 2:27)
Fletcher interprets this as: Jesus knew rules could be broken if it was for the good of humanity. The Sabbath rule existed to serve people's wellbeing; when it no longer served people, Jesus broke it.
Before You Enter a Moral Situation:
Accept these four presuppositions:
Once you've accepted these presuppositions, you can use the Six Propositions to guide your actual decision-making.
Easy Way to Remember:
Pragmatism ensures ethics isn't just abstract theory. It demands that moral decisions actually work in real life.
Relativism allows ethics to respond to unique situations. No rigid rules that fail in complex cases.
Positivism acknowledges that ethics ultimately rests on values we choose. This is honest about the limits of reason.
Personalism ensures people are never sacrificed for rules. Ethics remains human-centred.
We often cannot know in advance what will "work". How can we base ethics on outcomes we can't predict?
If there are no absolute rules, society becomes unstable.
Mother Teresa's Concern: Catholic critics argue that the stability of society is threatened by relativistic ethical theories like Fletcher's.
If accepting love is just a faith choice, why should anyone accept it? Those who don't share this faith have no reason to follow Situation Ethics.
If "people come before rules," couldn't you justify harming some people to help others? The principle doesn't specify which people to prioritise.
Catholics believe in ethical absolutes such as the sanctity of life. No matter what the pragmatic situation is, the value of life cannot be relativized. Fletcher's working principles of pragmatism and relativism are fundamentally wrong from this perspective.
"The good, like the true, is whatever works. Philosophy is utterly useless as a way to bridge the gap between doubt and faith. The situationalist follows a strategy which is pragmatic—exploring how moral views might play out in each real life situation, rather than trying to work out what to do in the abstract."
— Joseph Fletcher, Situation Ethics: The New Morality (1966)
Context: Fletcher explaining Pragmatism—the first working principle. Moral decisions must be practical and work in real life; abstract theoretical ethics is rejected in favour of focusing on what actually produces loving outcomes in specific situations.
"Any moral or value judgment in ethics, like a theologian's faith propositions, is a decision—not a conclusion. It is a choice, not a result reached by force of logic. Love is of people, by people, and for people. Things are to be used; people are to be loved. Loving actions are the only conduct permissible."
— Joseph Fletcher, Situation Ethics: The New Morality (1966)
Context: Fletcher explaining Positivism and Personalism—accepting agape as supreme is a faith decision, not a logical conclusion; and ethics must always put people at the centre, treating them as ends, not means.
| Principle | Meaning | Key Quote |
|---|---|---|
| Pragmatism | Actions must actually work to produce love in practice | "The good is whatever works" |
| Relativism | No absolute rules except love; right/wrong relative to situation | "Relativize the absolute, don't absolutize the relative" |
| Positivism | Accept agape on faith, not reason; it's a choice, not a logical conclusion | "A decision, not a conclusion" |
| Personalism | People come before rules; ethics is about human relationships | "Things are to be used; people are to be loved" |
Four Working Principles: presuppositions you must accept before applying Situation Ethics
Remember: "The Three P's and an R"—Pragmatism, Positivism, Personalism, Relativism
Pragmatism: actions must actually WORK to produce love in practice, not just in theory
Relativism: no absolute rules except love; "relativize the absolute, don't absolutize the relative"
Positivism: accept agape on FAITH, not reason—it's a choice, not a logical conclusion
Personalism: PEOPLE come before rules; "things are to be used; people are to be loved"
Jesus example: "The Sabbath was made for man, not man for the Sabbath"
Four Principles = foundations; Six Propositions = operational guidelines
Strength: practical, flexible, honest about faith, human-centred
Criticism: unpredictable, threatens stability, arbitrary faith basis, Catholics reject relativism
Safeguard: love is still the one absolute—everything else is relative to it
Together with Six Propositions, they form Fletcher's complete ethical system
