Jurisprudence
Law versus Morality
At a Glance ▪ Law and morality are both systems of ought and overlap heavily, but differ in source, scope, sanction, certainty, method of change and concern with the inner mind. The full theory is in Note 20. ▪ Thomasius gave the classic line: law governs the forum externum (outward acts), morality the forum internum (conscience). Kant separated legality (outward conformity, whatever the incentive) from morality (acting from duty). ▪ Law is not indifferent to the mind: it looks closely at intention and knowledge (mens rea), though motive is generally irrelevant to liability. Morality judges the motive itself. ▪ Jellinek called law the ethical minimum. Hart, a positivist, found a minimum content of natural law in five truisms about human nature; that is Hart, not Fuller. ▪ Indian courts now prefer constitutional morality to popular or public morality: Navtej Singh Johar (2018), overruling Suresh Kumar Koushal (2013), and Joseph Shine (2018). Shaw v DPP (1961) is the English contrast. |
Picture two referees at the same match. The first stands on the field with a whistle and can send a player off; he cares whether you tripped your opponent, not whether you felt sorry. The second referee sits inside each player's head: he has no whistle, only the voice of conscience and the frowns of the crowd, but he cares about everything, including what you intended and whether you played in the right spirit. That is the difference between law and morality: they usually agree about the worst fouls, but they are different officials with different powers. This note sets out, point by point, how they differ and where they meet.
1. The Two Systems Defined
Law, in the sense relevant here, is the body of rules recognised and enforced by the State through its courts (Salmond). Morality is the body of principles of right and wrong conduct accepted by a person or a society, backed by conscience and social opinion rather than by organised force. Both are normative: they tell people what they ought to do and furnish standards for judging conduct. Much of their content coincides (murder, theft, fraud), but each has rules the other lacks: the law requires driving on the left, and morality requires gratitude, which no court enforces.
2. The Historical Distinction: Thomasius and Kant
The sharp separation of the two is modern. Christian Thomasius (1655 to 1728), in his Fundamenta Juris Naturae et Gentium (1705), distinguished the forum externum, the domain of external acts in relation to others, which law may regulate and enforce, from the forum internum, the domain of the inner life and conscience, which belongs to morality and which coercion cannot reach. Law aims at outer peace; morality at inner peace.
Immanuel Kant, in The Metaphysics of Morals (1797), refined the point. Juridical legislation concerns only external actions and admits an external incentive (coercion); ethical legislation requires that duty itself be the incentive. The mere conformity of an action to law, irrespective of motive, is its legality; conformity in which the idea of duty is also the motive is its morality. A shopkeeper honest only for fear of losing customers acts legally but not, in Kant's sense, morally.
3. The Points of Difference
Basis | Law | Morality |
|---|---|---|
Source | Made or recognised by a determinate authority: legislature, courts, recognised custom | No single lawgiver; grows from conscience, religion, tradition and social opinion |
Domain (Thomasius) | Forum externum: outward conduct affecting others | Forum internum as well: thoughts, desires, character |
Mental element | Looks at intention, knowledge and negligence (mens rea); motive generally irrelevant to liability | Judges the motive itself; a right act from a bad motive is morally flawed |
Sanction | Organised, physical sanctions of the State: punishment, damages, nullity | Conscience, guilt, shame and social disapproval |
Enforcement | Through courts and officials, coercively | Through persuasion and opinion; not coercive |
Ascertainability | Relatively definite: statutes, precedents and custom determined by courts | Less definite; contested between persons and ages |
Uniformity | One law binds all within the jurisdiction | Varies between individuals, communities and religions |
Change (Hart) | Can be changed deliberately by enactment | Immune from deliberate change; alters slowly with opinion |
Aim | Social order and a minimum of conduct needed for common life | The good life and moral perfection of the individual |
Content | Includes morally neutral rules (traffic, forms, time limits) | Includes duties law does not enforce (gratitude, charity, truthfulness in private) |
4. The Differences Explained, with Two Corrections
Source and change. A statute can be passed or repealed on a stated date. Hart (The Concept of Law, 1961) found four features marking morality off from law: importance, immunity from deliberate change (no one can declare lying right from next Monday), the voluntary character of moral offences (no blame for what one could not help), and the form of moral pressure (appeals to conscience rather than threats).
Certainty: a correction. To call law 'definite and written' and morality 'vague and unwritten' overstates the point. The common law is judge-made and was never enacted, and custom is by definition unwritten (see Note 25). The better statement is that law is more ascertainable: whether written or not, there is an authoritative procedure, the courts, for determining what the law is. Morality has no such umpire.
The mind: a second correction. It is also said that law is satisfied 'whatever the motive'. That is true only of motive, not of the mental element generally. Criminal law is deeply concerned with intention, knowledge, recklessness and negligence: murder differs from culpable homicide, and both from accident, only by the state of mind (Section 103 BNS, formerly Section 302 IPC). What the law generally ignores is the ulterior reason for acting. A good motive does not excuse a crime (the mercy killer still kills intentionally), and a bad motive does not make a lawful act unlawful: in Bradford Corporation v Pickles (House of Lords, 1895), a landowner who drained water from his land to force the corporation to buy him out acted lawfully, however spiteful his motive. Motive still matters at the edges, as evidence and in sentencing. Morality, by contrast, judges the motive itself: the man who pays his debt only from fear of prison satisfies the law but not morality.
Sanction. Behind law stand courts, police and prisons; behind morality only conscience and opinion. Kelsen made the organised coercive sanction the mark of the legal order (see Note 12).
5. The Points of Contact
How law and morality meet ▪ Morality as a source of law. Equity, natural justice, good faith and reasonableness carry moral ideas into law. Section 23 of the Indian Contract Act, 1872 makes an agreement void if its object or consideration is immoral or opposed to public policy. ▪ Morality as a test of law. Natural lawyers from Aquinas onwards hold that an unjust law is not truly law (lex injusta non est lex). Radbruch's formula (1946) and Fuller's inner morality of law (1964) are modern versions (see Notes 9 and 65). ▪ Morality as a limit of law. Mill's harm principle (On Liberty, 1859) limits the reach of criminal law to conduct harming others. Constitutional rights now perform the same function in India. ▪ Law as shaping morality. Law can educate and change moral attitudes: the abolition of sati, of untouchability (Art. 17) and of dowry show legislation running ahead of popular morality and gradually changing it. ▪ Law as minimum morality. Georg Jellinek described law as the ethical minimum: the part of morality indispensable for social life, which society enforces by coercion. |
Hart's minimum content of natural law ▪ Hart, though a positivist, conceded that given certain truisms about human beings, any legal system that is to survive must contain certain rules, for example against violence, theft and deception. He called this the minimum content of natural law. ▪ The five truisms: human vulnerability, approximate equality, limited altruism, limited resources, and limited understanding and strength of will. This is natural necessity, not a claim that law must be just; law and morality remain conceptually separate. |
6. Kinds of Morality: Positive, Critical, Public and Constitutional
Positive morality is the morality actually accepted and shared by a given social group; critical morality is the set of general moral principles by which actual institutions, including positive morality itself, are judged. Hart used this pair in Law, Liberty and Morality (1963) to argue that the question whether law should enforce positive morality is itself a question of critical morality.
Indian constitutional law draws a parallel line between public (popular) morality, the majority's moral views at a given time, and constitutional morality, the values embedded in the Constitution: dignity, liberty, equality, fraternity and the rule of law. Dr Ambedkar told the Constituent Assembly on 4 November 1948, quoting the historian Grote, that constitutional morality is not a natural sentiment and has to be cultivated. The Supreme Court has held that where the two collide, constitutional morality prevails.
7. The Great Debates in Brief
Two famous debates are covered in full in Notes 20, 65 and 66; only the essentials are needed here. The Hart-Fuller debate (both papers in the Harvard Law Review, 1958; Fuller's The Morality of Law, 1964) asked whether there is a necessary connection between law and morality in deciding what counts as law. The Hart-Devlin debate, set off by the Wolfenden Report (1957), asked whether the law should enforce morality as such: Devlin's Maccabaean Lecture (1959; The Enforcement of Morals, 1965) said society may protect its shared morality, while Hart's Law, Liberty and Morality (1963) defended a modified harm principle.
8. The Indian Perspective and an English Contrast
Navtej Singh Johar v Union of India Supreme Court of India, 2018 (5 judges) Section 377 IPC was read down so far as it criminalised consensual sexual conduct between adults in private, overruling Suresh Kumar Koushal v Naz Foundation (2013), which had restored the provision after the Delhi High Court's decision in Naz Foundation (2009). The Court held that constitutional morality, not majoritarian social morality, governs the interpretation of fundamental rights. |
Joseph Shine v Union of India Supreme Court of India, 2018 (5 judges) The Court struck down the offence of adultery (formerly Section 497 IPC) as violating Arts. 14, 15 and 21: it treated the wife as the husband's property and punished only the man. Adultery may remain a moral wrong and a ground for divorce, but not a crime: what morality condemns, criminal law need not punish. |
S. Khushboo v Kanniammal Supreme Court of India, 2010 Criminal complaints against an actress for remarks on pre-marital sex were quashed: notions of social morality are inherently subjective, and criminal law cannot be used to interfere unduly with personal autonomy or punish unpopular views. |
Ranjit D. Udeshi v State of Maharashtra and Aveek Sarkar v State of West Bengal Supreme Court of India, 1965 and 2014 In Ranjit Udeshi (1965), concerning Lady Chatterley's Lover, the Court applied the English Hicklin test under the obscenity provision (formerly Section 292 IPC): whether the matter tends to deprave and corrupt those whose minds are open to such immoral influences. In Aveek Sarkar (2014) the Court abandoned Hicklin for the contemporary community standards test, judging the work as a whole. The legal measure of obscenity moved with public morality. |
Common Cause v Union of India Supreme Court of India, 2018 (5 judges) The Court recognised the right to die with dignity as part of Art. 21, permitted passive euthanasia and gave legal effect to advance directives (living wills) with procedural safeguards. |
Shaw v Director of Public Prosecutions House of Lords, 1961 The publisher of a 'Ladies' Directory' advertising prostitutes was convicted of conspiracy to corrupt public morals. Viscount Simonds asserted a residual power in the courts, as custos morum (guardians of morals), to protect the moral welfare of the State. It is the high point of judicial enforcement of public morality, the opposite pole to Navtej Singh Johar. |
Classic Definitions ▪ Thomasius: law concerns the forum externum (external acts, enforceable); morality the forum internum (conscience, not enforceable). ▪ Jellinek: law is the ethical minimum. ▪ Kant (The Metaphysics of Morals, 1797): legality is conformity of an action with law irrespective of its incentive; morality is conformity from the motive of duty. |
Memory Aid ▪ Analogy: two referees. Law is the referee on the field with a whistle and a red card; morality is the referee inside your head with no card but a view on everything, including why you did it. ▪ Thomasius in two words: 'Outside, Inside'. Forum externum = law (outside); forum internum = morality (inside). ▪ Hart's five truisms: 'VALLL'. Vulnerability, Approximate equality, Limited altruism, Limited resources, Limited understanding and strength of will. |
Exam Corner: Likely Questions ▪ Distinguish law from morality. Is law the 'ethical minimum'? ▪ 'Law regulates the external conduct of men, morality their inner life.' Examine with reference to Thomasius and Kant. ▪ Explain Hart's minimum content of natural law. Does it make Hart a natural lawyer? ▪ Distinguish public morality from constitutional morality with reference to Navtej Singh Johar and Joseph Shine. |
Exam Corner: MCQ Traps ▪ Forum externum and forum internum is Thomasius, not Kant or Austin. ▪ The minimum content of natural law is Hart, a positivist, not Fuller. Fuller's idea is the inner morality of law. ▪ Law as the ethical minimum is Jellinek. ▪ Navtej Singh Johar (2018) overruled Suresh Kumar Koushal (2013), not Naz Foundation (a Delhi High Court decision of 2009). ▪ Motive is generally irrelevant to liability, but intention is central: do not say law ignores the mind. |
9. Frequently Asked Questions
Q. What is the main difference between law and morality?
A. Law is made or recognised by the State, deals mainly with outward conduct and is enforced by organised sanctions. Morality has no single lawgiver, reaches motive and the inner life, and is backed only by conscience and opinion: Thomasius's forum externum against forum internum.
Q. Is it true that law ignores the state of mind?
A. No. Law pays close attention to intention, knowledge and negligence, which decide whether a killing is murder, culpable homicide or an accident. What law generally ignores is motive, the ulterior reason for the act: a good motive does not excuse a crime and a bad motive does not make a lawful act unlawful (Bradford Corporation v Pickles, 1895).
Q. What is the difference between public morality and constitutional morality?
A. Public morality is the moral opinion of the majority at a given time. Constitutional morality is the set of values embedded in the Constitution, such as dignity, liberty and equality. In Navtej Singh Johar (2018) the Supreme Court held that constitutional morality prevails where the two conflict.
