Person A argues: 'Moral constructivism just means that whatever people actually agree on is morally right.' Person B replies: 'Constructivism requires more than actual agreement — it specifies idealized conditions.' Who is correct?
APerson A — constructivism is defined by actual social agreement, which is what distinguishes it from moral realism
BPerson B — constructivism grounds moral truth in what idealized agents would endorse under specified conditions, not in what actual people happen to agree on
CBoth are correct — constructivism encompasses both actual and idealized agreement depending on which theorist you read
DNeither — constructivism holds that moral facts are simply constructed by legislators, not by any form of agreement
Person A is confusing constructivism with subjectivism or social-agreement theories. The key move in constructivism is idealization: moral truth tracks what fully rational, impartial agents would endorse under specified ideal conditions — not what actual people prefer. Rawls's veil of ignorance is paradigmatic: the principles you would choose not knowing your position in society, not the principles people actually advocate. Idealization is what gives constructed moral facts their objectivity and normative force.
Question 2 Multiple Choice
What primarily distinguishes moral constructivism from moral subjectivism?
AConstructivism holds that moral facts are mind-independent, while subjectivism denies this
BConstructivism grounds moral truth in idealized rational procedures, while subjectivism grounds it in actual preferences or feelings
CConstructivism applies only to political philosophy, while subjectivism covers all of ethics
DSubjectivism claims moral statements are true or false, while constructivism denies they have truth values
The crucial distinction is between actual and idealized. Subjectivism says moral truth tracks what actual people actually feel or prefer — your desire for X makes it (at least for you) good. Constructivism says moral truth tracks what idealized agents — fully rational, fully informed, freed of bias — would endorse through a specified procedure. Your actual preferences are not morally authoritative; the preferences you would have under ideal conditions are. This idealization separates constructivism from relativism and subjectivism and gives it a claim to objectivity.
Question 3 True / False
On a constructivist view, two different idealized procedures (such as Rawls's veil of ignorance and Scanlon's contractualism) could in principle yield different moral conclusions.
TTrue
FFalse
Answer: True
Different constructivist procedures specify different idealized conditions and ask different questions: Rawls asks what principles you would choose from behind a veil of ignorance about your social position; Scanlon asks what principles no one could reasonably reject. These are not equivalent and can yield different results on specific moral questions. The misconception that all constructivisms agree fails to notice that the moral output depends heavily on the procedural input.
Question 4 True / False
Moral constructivism holds that moral facts are discovered through rational procedures — just as mathematical truths are discovered rather than invented.
TTrue
FFalse
Answer: False
Constructivism holds precisely the opposite: moral facts are constructed through procedures, not discovered as pre-existing truths. The defining commitment of moral constructivism is that there are no mind-independent moral facts waiting to be found — the procedure creates the moral fact. This is what distinguishes constructivism from moral realism, which does hold that moral facts are discovered independently of any procedure.
Question 5 Short Answer
Explain why moral constructivism is not the same as moral subjectivism. What role does idealization play in giving constructed moral facts their objectivity?
Think about your answer, then reveal below.
Model answer: Subjectivism makes moral truth relative to actual individual or collective preferences: whatever you (or we) happen to prefer is thereby morally right. Constructivism rejects this by introducing idealization: moral truth is determined not by what actual people prefer, but by what idealized agents — fully rational, fully informed, impartial — would endorse through a specified procedure. Your actual preference for your own benefit is not morally authoritative; but the principle you would endorse not knowing whether you would be the beneficiary or the harmed party carries normative weight. Idealization removes the biases and self-serving reasoning that make actual preferences unreliable, stabilizing the moral output so it is determined by the procedure rather than by any individual's contingent feelings.
The gap between actual and ideal is where the philosophical action in constructivism lies. A student who misses this will conflate constructivism with the view that morality is just social convention or majority preference — which would make it arbitrary and variable across societies. The idealization is what gives constructed truths their objectivity and normative force.
