COMPARING THE SOCIAL CONTRACTS OF HOBBES AND
LOCKE
THOMAS MOURITZ
Abstract
Locke and Hobbes both share a vision of the social contract as instrumental in a state's
political stability. However, their respective philosophies were informed by a starkly
contrasting vision of human nature. This essay explores the historical context of each
philosopher and considers the differences in the social contractual theory that emerged
from their distinct perspectives on the state of nature.
I THE STATE OF NATURE AND THE SOCIAL CONTRACT
The notion of the social contract has been, quite simply, one of the most important
paradigms of Western philosophical and legal theory in helping to shape our
understanding of justice and social structure.1 Sharing some elements of thought, though
differing in many more, 17th
century Englishmen Thomas Hobbes and John Locke stand
out as amongst the most significant proponents of social contract theory. Held up
against the light of contemporary scrutiny, analysis may expose flaws and weaknesses
in their arguments. However, even more so it reveals that the sophisticated methods
they employed, the scope and structure in their observations of complex, ubiquitous
principles, and the depth of their impact in modern thinking ascribes them undeniable
stature and demonstrates the enduring value we can still gain from reviewing and
comparing their work on social contract theory.
Hobbes and Locke were not the first to use the social contract model as a tool to explain
the foundations of human society; earlier exponents of the theory can be traced much
further back in history. Arguably, elements of the social contract have existed as long as
ethical theories have been publicly espoused and recorded in writing.2 For example, in
Ancient Greece we find Plato‟s Republic describing a friendly communal debate about
the meaning of justice in which Thrasymachus and Glaucon introduce principles of
social contract theory,3 and conceptions of human nature,
4 that have been elaborated
upon by countless thinkers since, not least among them Hobbes and Locke. While the

„mechanical principles of materialism‟5 are generally emphasised as the shaping
foundations of both humanity‟s social contracts, it also has to be recognised that Hobbes
and Locke shared a grounding in the classics that was similarly influential in forming
their views on political philosophy and human behaviour.6
The links between the pair, both regarded for their social contract theory and with a
common debt to classical philosophy and to the influence of materialist thought, begin
to wane when the substance of their work is analysed more closely. Vastly different
individual circumstances helped define striking distinctions in personal outlook.
Hobbes‟ notably grim social contract theory, at its core reflecting what he believed was
the brutal, nefarious reality of instinctive human behaviour, was surely a product of a
worldview that could not overlook the troubled time he lived in. For much of his life,
Hobbes‟ world was one of political upheaval and war; the Thirty Years War was taking
place in Europe, and a Civil War drastically transformed political dimensions in
England. These extended periods of tumult fashioned a pessimistic outlook on human
nature, and instilled in Hobbes a strong conviction for an absolute monarchy, believing
that ultimately the only capable form of social governance was a sovereign with
„unrestricted ruling power‟.7
Locke reached his intellectual maturity in the more settled years after the English Civil
War, and was politically associated with the Whigs, who pushed for a limited
monarchy.8 He felt that an effective sovereign did not require absolute rule and, rather,
pushed for more individual freedoms. In fact, if we accept that the aim of Hobbes‟
social contract was to establish the necessary conditions for an all-powerful sovereign,
we find in turn that Locke‟s social contract had an altogether antipodean argument.
Partly as a result of his involvement in an attempt to prevent Charles II‟s royal
absolutist younger brother James from succeeding the throne, Locke‟s intention was to
justify the peoples‟ ability to resist absolute monarchy through rights granted in a mixed
constitution.9
Aware of the moulding contexts from which Hobbes and Locke arose, and the ultimate
conclusions that they were trying to reach and justify with their respective versions of
the social contract, we may then retreat to the essence of their theory and observe the
different ways in which they developed their arguments to achieve their goals, which in
turn provides ample opportunity for critical analysis.
One of Hobbes‟ defining features is the method in which he chooses to relate his social
contract. Hobbes was adamant that a rigorous, rational argument was necessary to cure
the ills of an ailing state political structure based on „bad reasoning‟.10

he was convinced that sound reason must possess geometric precision,11
and therefore
opted to enhance the scientific certainty of his thesis with the formal legality of contract
theory.12
While the integration of legal theory into his political philosophy lent support
to Hobbes‟ „individualistic metaphysics‟,13
ultimately the contractual premise that
Hobbes sets forth has come to be questioned in its final conclusion as unconvincing in a
strict legal sense.
Calculatedly removing any sentimental notions about humanity‟s inherent virtue,
Hobbes‟ theory began with a belief that people in an original state of nature are
primarily interested in preserving their own lives, even if that meant destroying the life
of another. This proliferation of self-interested individuals creates a state of perpetual
conflict with each other, or universal war.14
Humanity‟s self-interest in turn obliges him
to seek a path out of this violent state towards peace and freedom from pain and anxiety,
where he can pursue pleasure.15
This leads to the first step in Hobbes‟ social contract.
To avoid war, all individuals must enter into a covenant with every other person,
agreeing not to harm one another. This agreement alone, however, is not sufficient to
maintain peace.16
Compliance with this social contract requires the coercive power
which Hobbes believed only a powerful sovereign could provide. Merely placing trust
in an unadorned, non-binding agreement between individuals is not just imprudent, but
unlawful according to Hobbes.17
The social contract‟s success depends on the
immediate institution of a sovereign upon whom individuals have surrendered all
liberty,18
and who is able to ensure obedience both to natural law and whichever
commands he delivers.19
Hobbes‟ sovereign power is not a party to the social contract,
but instead a recipient of the powers conferred upon him when all under the sovereign
enter the universal compact and sacrifice their liberty in the process.20
Many commentators believe that by placing all faith in the sovereign to enforce the
social contract, Hobbes‟ theory fails to reach the standard of ultimate and convincing
proof in a strictly legal sense. Hobbes‟ main weakness is that he is never able to explain
why one should not break the social contract and disobey the sovereign, which seems to
be little more than a moral responsibility.21
The typical legal answer to the question of
enforcing a contract would be that the courts will uphold the law; in the state of nature,
without an established system of jurisprudence, Hobbes has difficulty in responding to

the problem of enforcing and upholding the contract.22
Further undermining the
persuasion of Hobbes‟ argument is that his social contract is essentially hypothetical,
and seems to have no obvious parallel in history. In the end, Hobbes must admit that it
is fear alone that keeps humanity complying in subjection.23
Locke‟s theory is similarly compromised by the “historical objections to the social
contract”, however, he intended to demonstrate a rational argument rather than relate a
practical example.24
In reality though, his more digestible argument founded on notions
of equality and rights to property would find itself powerfully expressed in the
constitutional foundations of the United States of America, where the Declaration of
Independence is closely modelled on elements of Locke‟s Second Treatise of
Government.25
Locke‟s state of nature is free of Hobbes‟ „force and fraud‟, with men instead „living
together according to reason‟ but without a guiding authority to follow. Naturally,
individuals are inclined to avoid a solitary life, and inevitably start a family, which
eventually leads to the formation of political society.26
The social contract has a two-
step progression: firstly from individuals to collective society, and secondly a „vesting
of power in the legislature as a trust.‟27
Contrary to Hobbes‟ society, where rights are
sacrificed entirely in fear, the power placed in the legislature is in Locke‟s opinion „a
positive, voluntary grant and institution.‟28
The obligation is for the government to serve
the people, and the right of the public to resist authority is fundamentally inherent and
unable to be compromised.29
Locke‟s strong assertion of the natural right to property further sets his doctrine apart
from Hobbes. Locke expanded the conventionally accepted notion that humanity
possesses a private property right over their own body, elaborating further that the
property one‟s body cultivates is also an integral component of the basic freedom and
dignity which all are equally owed.30
He considered that this right existed, but was not
sufficiently protected, in a state governed by natural law, and thus it was necessary to
integrate the right to property as a fundamental element of his social contract.31
Locke‟s doctrine of „government by consent of the governed‟,32
with its palatable and
contemporarily attractive principles of limitation of government, and prevention of the

interference of natural rights including property, has seen his writing retain relevance
and manifest with material impact in politics to this day. In reality, however, his social
contract is little more than a general model or structure to contain his arguments, and
amounts to little more than a one-way trust between „a government obligated to the
people, (and) not they to it.‟33
Ultimately, the social contract is not as fundamentally
essential to Locke‟s theory as it is for Hobbes.
