Hilary Putnam’s concept of the “division of linguistic labor” (introduced in his 1975 essay The Meaning of ‘Meaning’) is central to understanding how knowledge is distributed across society. While originally applied to language and meaning, it has broader implications for knowledge acquisition and reliance on others for understanding the world. Putnam used examples like identifying natural kinds (e.g., water, gold) to argue that no single person knows everything about a word’s referent, but instead we rely on experts and social systems to fix meaning and knowledge.

Let’s expand this concept of the division of labor in knowing with concrete domains, such as tree identification, food knowledge (production and consumption), and general knowledge in society.

1. Identification of Trees and Natural Kinds

Putnam uses the example of “elm” and “beech” trees: many people can use these words correctly in conversation without being able to distinguish the trees themselves. This is possible because:

Experts such as botanists or arborists can correctly identify and classify trees.
Non-experts rely on these experts (and social-linguistic conventions) for the terms to have stable reference.
Therefore, linguistic competence doesn’t require full epistemic competence—you can “know” what an elm is (in a functional sense) without being able to identify one.

This reflects a division of labor: some people in society are tasked with maintaining the detailed knowledge required to secure accurate reference, and the rest of us benefit from their expertise without needing to replicate it.

2. Knowledge of Food: Production and Consumption

Most people eat food every day but lack direct knowledge of:

Where or how it was grown (e.g., soil conditions, pesticides used)
How it was processed (e.g., milling of grains, food safety steps)
Its nutritional and chemical composition

Here, Putnam’s insight applies as follows:

We trust farmers, food scientists, nutritionists, chefs, and regulators to have specialized knowledge about food.
We rely on labels, dietary guidelines, and norms to make decisions without personally verifying the biochemical properties of each ingredient.
This is a clear example of epistemic division: different stages of the food system are understood and managed by different kinds of knowers.

Thus, the consumer’s knowledge is deferred and mediated through institutional expertise and social trust.

3. General Knowledge and Society

Putnam’s idea generalizes beyond trees and food. In almost any area of modern life—technology, law, medicine, engineering—we see a complex division of cognitive labor:

No single person knows how an airplane works and how to perform heart surgery and how to build a semiconductor chip.
Yet people navigate modern life effectively because they trust and rely on experts in each domain.
This structure reduces individual cognitive burdens and allows society to advance by aggregating distributed knowledge.

4. Implications

Social Epistemology: Knowledge is not just an individual achievement but often a social accomplishment.
Deference to Experts: Much of what we “know” is really knowing who knows—or trusting institutional mechanisms (science, journalism, academia).
Language as a Social Tool: Words refer not just by what the speaker knows, but by what the community knows.
Cognitive Efficiency: Division of labor enables humans to specialize, increasing overall societal knowledge without requiring each individual to master every subject.

5. Challenges

Epistemic Dependence vs. Autonomy: Over-reliance on experts can lead to disempowerment or misinformation if trust is misplaced.
Access to Expertise: Inequalities in access to education or reliable information can skew the benefits of this system.
Mistrust and Polarization: In a fragmented media environment, people may trust different “experts,” challenging the coherence of the division of labor.

Summary

Putnam’s division of labor in knowing highlights how modern knowledge is socially distributed, relying on specialists to maintain accuracy and laypeople to defer appropriately. Whether it’s identifying a tree, understanding food origins, or navigating complex technologies, individuals participate in a network of knowledge that exceeds their personal epistemic limits. This framework is foundational to understanding how societies manage knowledge, build trust, and function in an interdependent world.
