The shifting paradigm in public health represents a transition from a narrow focus on treating diseases to a holistic and preventive approach. Emphasizing proactive measures, community engagement, and a broader understanding of health determinants, this new perspective aims to prevent issues before they occur. It reflects a commitment to creating inclusive and sustainable health systems that prioritize overall well-being.

1. The ideas of the ruling class are in every epoch the ruling
ideas, i.e. the class which is the ruling material force of
society, is at the same time its ruling intellectual force. The
class which has the means of material production at its
disposal has control at the same time over the means of
mental production, so that thereby, generally speaking, the
ideas of those who lack the means of mental production
are subject to it. The ruling ideas are nothing more than the
ideal expression of the dominant material relationships, the
dominant material relationships grasped as ideas.

3. • Methodological individualism (MI) is a concept from the
19th century which played a major role in the history of
ideas and ideologies.
• It is a type of materialistic metaphysics and nominalist
epidemiology and has prominent influence in social
science research till this day.
• It suggests that understanding society comes from
studying the actions and behaviors of individuals.
• MI originated with Thomas Hobbes, who believed society
is formed by interactions among competitive individuals
with innate drives.
11/4/2023 4

4. • Other thinkers expanded on this idea, explaining society
through individualistic perspectives.
• During the Renaissance, people started seeing
themselves as separate from the collective.
• However, Auguste Comte believed that society cannot be
reduced to individuals, similar to how a geometric surface
cannot be reduced to lines or points.
• John Stuart Mill, an early advocate of MI, believed social
phenomena can only be explained by studying individual
human nature.

5. 5.1 LESSONS FROM THE
SOCIOLOGY OF
KNOWLEDGE

6. • Joseph A. Schumpeter coined the expression MI in 1942
and described it as an exclusively scientific strategy that
focuses on the actions of individuals when studying
certain economic processes.
• His ideas influenced notable thinkers such as Hayek
(1948), Popper (1966), and JWN Watkins (1957), among
others.
• They argued that social phenomena should be
understood as a result of human action and criticized
explanations that relied solely on collectives.
11/4/2023 7

7. • Popper, in particular, emphasized the rejection of
explanations based on so-called collectives and
highlighted the importance of understanding individual
actions.
• Hayek and Watkins believe that understanding social
phenomena involves studying the actions and
characteristics of individuals.
• Hayek thinks we can understand social phenomena by
interpreting others' intentions and plans.
• Hayek wrote in “the Facts of the Social Science” that we
understand what other people tell us, and can be
understood only by interpretation other people’s
intentions’ and plans
11/4/2023 8

8. • Watkins says that any social tendency can be changed if
individuals want to change it and have the right
information.
• Both Hayek and Watkins explanations based on groups of
people are not enough.
• Hayek mentions that understanding different types of
beings can be challenging, sometimes requiring an
objective approach.
• Watkins excludes physical factors we can't control from
his definition of "social" tendencies.

9. Methodological Individualism (MI):
• Emphasizes explaining social phenomena by focusing
on individuals.
• Argues that understanding individual thoughts, actions,
and relationships is crucial.
• Believes large-scale social phenomena are best
explained through individuals.
Sociological Holism/Organicism:
• Views social systems as "wholes" with their own
governing laws.
• Emphasizes macro-level explanations specific to
society.
• Holds that individual behavior is influenced by these
sociological laws.
11/4/2023 10

10. Ideologists:
• Emile Durkheim:
• Recognizes the importance of collective consciousness.
• Considers individualism as a product of society.
• Views individualism as a unifying force for modern
society.
• Max Weber:
• Highlights the significance of individual actions and their
subjective meanings.
• Argues for understanding social explanations through
individual actions and understandings.
• Advocates focusing on individuals rather than abstract
concepts like social structures.
11/4/2023 11

11. • In summary, there is a debate between methodological
individualism and sociological holism.
• Durkheim emphasizes the role of collective
consciousness and sees individualism as a unifying force.
Weber stresses the importance of individual actions and
subjective meanings when explaining social phenomena.

12. 5.2 BREAKING DOWN
NEOCLASSICAL ECONOMICS:
THE POWER OF
METHODOLOGICAL
INDIVIDUALISM

13. • Economics, like other social sciences and
psychology, was influenced by scientism,
particularly mechanics.
• The mechanistic view from natural sciences, with
its mathematical tools, had a significant impact on
economics.
• Neoclassical economics, influenced by mechanistic
epistemology, dominates economic theory and
focuses on maximizing individual behaviors.
11/4/2023 14

14. Classical political economy vs. neoclassical
economics:
• Classical political economists like Adam Smith,
David Ricardo, and Karl Marx analyzed advancing
capitalist economies in terms of social relations
and social groups.
• Neoclassical economics introduced a shift in the
unit of analysis, focusing on individuals rather than
social groups.
11/4/2023 15

15. Methodological individualism in economics:
• Methodological individualism (MI) in economics
emphasizes the decisions and actions of individual
agents as the basic unit of observation and
analysis.
• MI aims to distinguish itself from psychologism and
subjectivism, but it overlooks social factors and
qualitative differences in behavior due to an
individual's social group.
11/4/2023 16

16. Walrasian general equilibrium theory and neoclassical
economics:
• The Walrasian general equilibrium theory describes the
economy as a harmonious system where individuals make
independent decisions.
• This theory assumes autonomous individuals, reversible
decisions, and ignores the hysteresis effect.
• Such assumptions mimic mechanistic methods applied to
freely moving particles, lacking a historical dimension.
11/4/2023 17

17. Austrian school and methodological
individualism:
• The Austrian school, associated with
methodological individualism, considers the actions
and decisions of individual agents as the focus of
observation and analysis.
• Austrian Aristotelianism emphasizes strict
universality of laws and the recognition of general
recurring structures in the flux of reality.
11/4/2023 18

18. Contrasts between methodological holism and
methodological individualism:
• Marx and Menger shared an antipathy towards atomism but
had radically different views on holism and individualism.
• Marx advocated for holism and ontological collectivism,
focusing on establishing general laws of development.
• The Austrian school favored methodological individualism
and ontological individualism, treating social wholes as
eliminable shorthand for individuals.
11/4/2023 19

19. Hayek's concept of human liberty:
• Hayek valued liberty as the absence of coercion and
considered natural-social disadvantages as akin to a
lottery rather than coercion.
• He dismissed the legitimacy of collective infringement on
individual liberty, equating it to random distribution of
constraints.
Keynes and the challenge to neoclassical economics:
• John Maynard Keynes challenged neoclassical
economics during the Great Depression, questioning the
reliance on the atomistic laissez-faire competitive system
11/4/2023 20

20. • Classical political economy: Focuses on social relations and
social groups as drivers of economic change.
• Neoclassical economics: Shifts focus to individual behavior
and maximizing objectives, treating society as a collection of
independent individuals.
• Methodological individualism (MI): Emphasizes individual
decisions as the basic unit of analysis, neglecting social factors
and qualitative differences.
• Austrian school of economics: Advocates for MI and
believes in universal laws governing economic phenomena.
• Neoclassical economics flaws: Assumes equilibrium with
independent and reversible decisions, ignores historical context
and social processes.

Conclusion of chapter 5.2

21. Conclusion
• Methodological individualism (MI) is a perspective in the
sociology of knowledge that emphasizes explaining social
phenomena solely through individual human actions.
• MI is contrasted with methodological holism, which
highlights social determination and macro structural
explanations.
• Prominent proponents of MI include Hobbes, Mill, Weber,
Schumpeter, Popper, Hayek, and Elster.
11/4/2023 22

22. Conclusion
• The Durkheimian and Weberian versions of individualism have
influenced the development of individualism in public health
discourse.
• Neoliberal economics, influential in public health, has also shifted
towards individualism through schools like the Walrasian,
Austrian, and Chicago schools.
• This shift detached economic discourse from holism and
emphasized the concept of a 'free' rational agent making choices
in an open market.
• The individualistic perspective tends to be ahistorical and
overlooks the constraints that limit choices.
