I. Introduction: Spinoza and the Problem of Historical Materialism
Baruch Spinoza occupies a singular position in the history
of philosophy: a thinker simultaneously canonised and neutralised. He is
celebrated as a rationalist metaphysician, admired as a pioneer of secular
modernity, and invoked as a precursor to democratic thought. Yet these
recognitions have often come at the cost of stripping his work of its
revolutionary implications. Contemporary scholarship, even when sympathetic,
tends to isolate Spinoza from the social antagonisms of the seventeenth century
and from the radical traditions that later drew upon his ideas. Spinoza’s ideas
were “dangerous in his own time, and remain dangerous today,” precisely because
they undermine every ideological justification for hierarchy, privilege, and
clerical authority.
2.Spinoza’s Life as a Historical Symptom
Spinoza’s biography is not an incidental backdrop to his
philosophy; it is a historical symptom of the contradictions of the Dutch
Republic. Born into Amsterdam’s Portuguese‑Jewish community a community of former conversos who had fled
the Inquisition Spinoza was
excommunicated at twenty‑three for “abominable heresies” and “monstrous deeds.”
The severity of the cherem reveals the political anxieties of a
mercantile‑rabbinic elite dependent on the Republic’s fragile tolerance.
Spinoza’s ideas threatened not only theological orthodoxy but the ideological
foundations of a commercial oligarchy.
His modest life as a lens‑grinder, his clandestine
publications, and his sympathy for Jan de Witt’s republicanism all point to a
thinker whose material circumstances were inseparable from his philosophical
commitments. His attempt to denounce de Witt’s murder as “barbaric” an act his landlord prevented for fear of
reprisals illustrates the political
stakes of his thought. Spinoza’s biography thus becomes a site where
intellectual history and class struggle intersect.
Leon Trotsky’s method of “concrete analysis of concrete
conditions” is indispensable here. Spinoza’s intellectual defiance cannot be
understood apart from the class forces that shaped the Dutch Republic: the rise
of a commercial bourgeoisie, the crisis of feudal remnants, and the ideological
vacuum created by the decline of scholasticism. Spinoza’s philosophy emerges
not as an abstract system but as the rational expression of a world in
transition.
3.Monism as the Ontological Ground of Materialism
Spinoza’s rejection of Cartesian dualism is the decisive
philosophical rupture that makes modern materialism possible. Descartes’
division of reality into res cogitans and res extensa preserved
the theological worldview of the seventeenth century. Spinoza demolished this
architecture by asserting that there is only one substance “God or Nature (Deus
sive Natura).” Thought and extension are attributes of the same substance; the
mental and the physical are two expressions of one reality.
This monism is not a metaphysical curiosity but the
ontological foundation of materialism. By dissolving the supernatural realm,
Spinoza undermines the ideological authority of church and state. His claim
that “the order and connection of ideas is the same as the order and connection
of things” anticipates Marx’s insistence that consciousness is a product of
material conditions. Spinoza’s monism thus becomes the conceptual precondition
for a scientific account of society.
Trotsky’s dialectical materialism deepens this insight. For
Trotsky, the unity of mind and world is not merely ontological but historical:
consciousness develops through labour, social relations, and class struggle.
Spinoza’s monism provides the ontological ground; Marx and Trotsky provide the
historical and dialectical method.
4.Consciousness, the Body, and the Anticipation of Marx
Steven Nadler’s argument is that consciousness corresponds
to bodily complexity, citing Spinoza’s remark that “in proportion as a body is
more capable… so its mind is more capable.” This insight dissolves the
Cartesian “hard problem” centuries before its formulation. Consciousness is not
an immaterial substance but the mental expression of a body embedded in causal
networks.
Marx radicalises this insight by adding the historical
dimension. Consciousness is not only the correlate of a complex body but of a
body transformed by labour, tools, and social relations. When Marx writes that
“consciousness can never be anything else than conscious being,” he completes
the trajectory that begins with Spinoza’s monism. Spinoza provides the
ontology; Marx provides the anthropology and the historical method.
Trotsky extends this further. In Problems of Everyday
Life, he insists that consciousness is shaped by the rhythms of production,
the organisation of labour, and the ideological apparatuses of class society.
Spinoza’s insight into the embodied nature of consciousness becomes, in
Trotsky’s hands, a theory of revolutionary consciousness: the capacity of the
working class to grasp the necessity of social transformation.
5.Spinoza and Trotsky on Necessity, Freedom, and
Determinism
The question of necessity and freedom occupies a central
place in both Spinoza’s philosophy and the Marxist tradition. Yet the
conceptual architectures through which each thinker approaches the problem
differ in form while converging in political and historical significance.
Spinoza articulates a monistic determinism in which freedom consists in the
adequate understanding of necessity; Trotsky, working within the framework of
dialectical materialism, transforms this insight into a theory of revolutionary
praxis in which freedom emerges through the conscious intervention of the
working class into historically determined processes. The comparison reveals
not only a deep structural affinity but also the way in which Marxism completes
and historicises Spinoza’s project.
Trotsky’s theory of permanent revolution provides the
conceptual framework for understanding Spinoza’s political significance.
Spinoza’s democratic republicanism anticipates the bourgeois revolutions of the
eighteenth century, but it also contains the seeds of a more radical
egalitarianism that can only be realised through proletarian revolution.
Spinoza’s critique of superstition becomes, in Marxist hands, a critique of
ideology; his defence of democracy becomes a defence of workers’ democracy; his
monism becomes the ontological ground of dialectical materialism.
6 Spinoza: Freedom as the Understanding of Necessity
Spinoza’s determinism is absolute. Everything that exists
follows from the nature of substance with the same necessity with which the
properties of a triangle follow from its essence. Human beings, as finite
modes, are no exception. Our actions, desires, and thoughts are determined by
the causal order of nature; the experience of free will is an illusion born of
ignorance of the causes that determine us. As the uploaded document notes, for
Spinoza “freedom… is not free will but the understanding of necessity.”
This conception of freedom is not merely metaphysical but
ethical and political. To understand necessity is to liberate oneself from the
bondage of passive affects, superstition, and ideological mystification.
Spinoza’s critique of religious authority rests on this insight: superstition
thrives where causal understanding is absent. Freedom, therefore, is the
achievement of adequate ideas — a rational comprehension of the causal order
that governs both nature and society.
Yet Spinoza’s determinism is not fatalistic. The more we
understand the causes that determine us, the more we participate in the
activity of substance itself. Freedom is not the negation of necessity but its
conscious appropriation. This is the conceptual core that Marx and Trotsky will
later radicalise.
7. Trotsky: Freedom as Conscious, Collective Praxis
Trotsky inherits Spinoza’s insight that freedom is
inseparable from necessity, but he transforms it by embedding it within a
historical and social framework. For Trotsky, necessity is not the static
causal order of nature but the dynamic, contradictory movement of history
shaped by class struggle, technological development, and the global expansion
of capitalism. Freedom emerges not through individual rational insight but
through collective revolutionary praxis.
Trotsky’s critique of voluntarism and fatalism alike
reflects this dialectical conception. Against voluntarism, he insists that
revolutionary action must be grounded in an analysis of objective conditions;
against fatalism, he argues that these conditions do not determine outcomes
mechanically but open possibilities that can be realised only through conscious
intervention. The working class becomes the agent through which necessity is
transformed into freedom.
In The Revolution Betrayed, Trotsky writes that
“freedom is the recognition of necessity — and the transformation of necessity
into action.” This formulation echoes Spinoza but adds a crucial dimension: the
transformation of necessity is a historical process, not a metaphysical one.
Where Spinoza locates freedom in the intellect, Trotsky locates it in praxis.
8. Determinism Without Fatalism: A Shared Structure
Both Spinoza and Trotsky reject the notion of free will
understood as uncaused choice. Both insist that human action is determined by
causes that can be understood and acted upon. Both oppose superstition,
mystification, and ideological obfuscation. Yet neither collapses determinism
into fatalism.
For Spinoza, determinism is the condition of freedom: only
in a universe governed by necessity can rational understanding liberate us from
passive affects. For Trotsky, determinism is the condition of revolutionary
agency: only in a world governed by historical laws can the working class
intervene consciously to transform society.
The difference lies in the level of analysis. Spinoza’s
determinism is ontological; Trotsky’s is historical. Spinoza’s freedom is
intellectual; Trotsky’s is political. Spinoza’s subject is the rational
individual; Trotsky’s is the revolutionary class.
Yet the structural affinity is unmistakable. Trotsky’s
dialectical materialism can be read as the historical realisation of Spinoza’s
monism: the unity of mind and world becomes the unity of theory and practice;
the understanding of necessity becomes the transformation of necessity; the
critique of superstition becomes the critique of ideology.
9. Necessity and Freedom in Revolutionary Time
The most profound convergence between Spinoza and Trotsky
lies in their shared rejection of contingency as the foundation of human
action. For both thinkers, freedom is not the assertion of arbitrary will but
the alignment of human activity with the causal structure of reality. In
Spinoza, this alignment is achieved through adequate ideas; in Trotsky, through
the scientific analysis of capitalism and the strategic organisation of the
working class.
Trotsky’s theory of permanent revolution exemplifies this
synthesis. The revolution is not a voluntaristic leap but the unfolding of
historical necessity — the contradictions of combined and uneven development —
realised through conscious action. Spinoza’s dictum that “the more we
understand, the more we are free” becomes, in Trotsky’s hands, “the more the
working class understands the laws of history, the more it can transform them.”
10. Completing Spinoza: Marxism as the Historical
Realisation of Monism
The comparison reveals that Marxism does not break with
Spinoza but completes him. Spinoza provides the ontological foundation: the
unity of mind and world, the determinism of nature, the critique of
superstition. Marx and Trotsky provide the historical and political
realisation: the unity of theory and practice, the determinism of history, the
critique of ideology.
Spinoza dissolves dualism; Marx dissolves idealism; Trotsky
dissolves fatalism. Spinoza grounds equality in nature; Marx grounds it in
social relations; Trotsky grounds it in revolutionary praxis. Spinoza’s freedom
is the understanding of necessity; Trotsky’s is the transformation of
necessity.
In this sense, Trotsky is the most Spinozist of Marxists —
not because he repeats Spinoza’s metaphysics, but because he realises its
deepest implications in the sphere of history and revolution.
11 Politics, Ideology, and the Democratic Lineage
Spinoza’s political radicalism emerges directly from his
metaphysics. If all humans are modes of the same substance, then no divine
hierarchy can justify monarchy or clerical authority. His defence of democracy,
equality, and secularism is not an ethical preference but a logical consequence
of his ontology. His critique of superstition anticipates Marx’s analysis of
ideology: both identify false consciousness as the mechanism through which
domination is reproduced.
Jonathan Israel’s argument that Spinoza was the first major
modern democrat is historiographically significant, but a Trotskyist analysis
must go further. Spinoza’s political thought is not merely democratic; it is
revolutionary. It articulates the emerging interests of a class whose ascent
threatened the existing order. Ann Talbot’s claim that Spinoza was “as
responsible as any one person could be for the revolution in consciousness”
preceding the Enlightenment captures this dynamic.
12. The Line of Descent: Spinoza → French Materialism →
Marxism
The connection between Spinoza and Marx is not retrospective
but genealogical. The French materialists — La Mettrie, Diderot, d’Holbach —
absorbed Spinoza’s monism and transformed it into a militant atheism that
confronted the ideological apparatus of absolutism. Plekhanov’s assertion that
“present‑day materialism is a Spinozism that has become more or less aware of
itself” captures this continuity. Engels’s remark — “Old Spinoza was quite
right” — confirms that Marxism recognised Spinoza as a precursor.
This lineage is not a chain of influence but a sequence of
determinate historical transformations. Spinoza’s nature becomes Marx’s social
totality. Spinoza dissolves dualism; Marx dissolves idealism. Spinoza grounds
equality in nature; Marx grounds it in social relations and class struggle.
Trotsky’s contribution is decisive here. He insists that
materialism must be historical and dialectical, capable of analysing the
contradictions of capitalism and the dynamics of revolution. Spinoza’s monism
becomes, in Trotsky’s hands, a weapon against both idealism and mechanical
materialism. The unity of mind and world becomes the unity of theory and
practice; the critique of superstition becomes the critique of Stalinist
mystification; the defence of democracy becomes the defence of workers’ democracy
against bureaucratic degeneration.
13. Scruton and the Conservative Neutralisation of
Spinoza
The uploaded document’s contrast between Spinoza and Roger
Scruton is a model of Trotskyist ideological critique. Scruton’s work
represents the conservative attempt to reclaim Spinoza by stripping him of his
revolutionary content. He admires Spinoza’s logical rigour but rejects the
egalitarian implications of his monism. He transforms Spinoza into a
philosopher of aesthetic consolation, a thinker whose metaphysics can be
reconciled with hierarchy, tradition, and the “sacred.”
This is not an innocent misreading but an ideological
operation. Scruton’s conservatism is “the ideological antithesis of Spinoza’s
rationalism.” Where Spinoza dissolves the sacred, Scruton elevates it; where
Spinoza undermines hierarchy, Scruton defends it; where Spinoza insists that
social reality can be understood and transformed, Scruton insists it must be
accepted. Trotsky would recognise this immediately as the reactionary function
of philosophy under conditions of capitalist crisis.
Scruton’s domestication of Spinoza mirrors the Stalinist
domestication of Marx: both seek to neutralise revolutionary thought by
detaching it from its historical and materialist foundations. A Trotskyist
historiography exposes these operations and restores Spinoza to the
revolutionary lineage from which he has been severed.
14. Conclusion: Spinoza in the Age of Global Capitalism
Spinoza’s revival reflects the exhaustion of postmodernism
and the crisis of bourgeois philosophy. As the ideological coherence of
neoliberalism collapses, the materialist tradition — from Spinoza to Marx to
Trotsky — re‑emerges as the only framework capable of explaining consciousness,
politics, and social transformation. Spinoza was a revolutionary in the Dutch
Republic; his ideas remain revolutionary under global capitalism. Marxism does
not supersede Spinoza but completes him.
Spinoza’s monism becomes the ontological ground of
dialectical materialism; his critique of superstition becomes the critique of
ideology; his defence of democracy becomes the defence of workers’ democracy;
his rationalism becomes the rationality of revolutionary praxis. In an era
marked by deepening inequality, ideological disorientation, and the global
crisis of capitalism, Spinoza’s rational, egalitarian, and naturalistic
worldview offers not a relic of the past but a resource for the future. Only Marxism,
as the dialectical completion of Spinoza’s project, can realise its
emancipatory potential.
