Who should I choose for empiricism in a psychology history paper?

John Locke is the strongest choice. His tabula rasa concept directly challenged fixed notions of human nature and laid the groundwork for observation-based psychological study. His political philosophy also influenced reformers like Dorothea Dix who argued for humane treatment of the mentally ill.

Who represents rationalism in the history of psychology?

René Descartes is the most commonly selected rationalist for psychology papers. His mind-body dualism created the philosophical foundation for studying the mind as a distinct, rational object — moving explanations of mental illness away from theology toward medical science.

How did empiricism, rationalism, and naturalism lead to humanitarian reform?

Empiricism established observable evidence as the standard for knowledge — reformers like Dorothea Dix used documented evidence of suffering to argue for change. Rationalism reframed mental illness as a medical rather than moral problem, making rational treatment the logical response. Naturalism removed moral blame from patients by positioning mental illness as a biological phenomenon, directly challenging punitive asylum practices.

How many pages should this psychology paper be?

The standard assignment is six pages: a title page, four pages of content (introduction, three thinker sections, reform analysis, modern impact, conclusion), and a reference page. Content pages should be double-spaced in APA 7th format with 1-inch margins.

Empiricism, Rationalism & Naturalism

Understanding the Assignment

What This Paper Is Actually Asking You to Do

The Core Task

You are tracing a historical argument: three philosophical traditions (empiricism, rationalism, naturalism) each produced thinkers whose ideas changed how psychology was studied — and those changes eventually drove real-world reforms in how society treated people with mental illness. Your paper needs to connect all three threads.

The assignment has two distinct halves. The first half is biographical and analytical — who were these thinkers, what did they actually contribute, and why did it matter to psychology? The second half is about consequences — how did those intellectual shifts lead to humanitarian reform, and what does that reform look like in today’s mental health system?

Students often write the first half well and then treat the second half as an afterthought. Your paper needs equal depth across both sections. A strong conclusion draws the full arc: from 17th-century philosophy to 21st-century psychiatric care.

💡

Pick one thinker per tradition — don’t try to cover several

You have roughly six pages. One thinker per system, treated deeply, is far stronger than three thinkers per system treated shallowly. Choose the thinker whose work most clearly connects to the humanitarian reform argument you plan to make.

Part One — The Three Thinkers

Which Thinker to Choose (and What to Say About Them)

Below are the strongest candidates for each tradition. Each card shows who the thinker was, their core contribution, and the key essay angle that connects their work to psychology and reform. Pick one per column.

E

Empiricism

Best choice: John Locke

Locke argued that the mind begins as a blank slate (tabula rasa) — all knowledge comes from sensory experience, not innate ideas.

Challenged the idea that mental illness was spiritual or fixed by birth
Laid the groundwork for observation-based psychological study
His political philosophy directly influenced asylum reform
Essay angle: if minds are shaped by experience, environments matter — reformers used this to argue for humane conditions

R

Rationalism

Best choice: René Descartes

Descartes separated mind from body (mind-body dualism) and argued that reason, not just faith or tradition, was the path to understanding human nature.

Created philosophical space for a science of the mind separate from theology
His mechanistic view of the body encouraged systematic study of behavior
Mind-body split influenced early psychiatry — mental illness could be studied rationally
Essay angle: rationalism shifted explanations of madness from sin to science

N

Naturalism

Best choice: Charles Darwin

Darwin’s theory of evolution through natural selection reframed human behavior and mental life as products of biology and adaptation.

Positioned psychology as a natural science — behavior could be studied empirically
Influenced William James and early comparative psychology
Evolutionary framework made mental illness a biological, treatable phenomenon
Essay angle: naturalism removed moral blame from mental illness, enabling medical treatment

📌

Alternative thinkers if your course specifies different names

Empiricism alternatives: Francis Bacon (scientific method), David Hume (associationism), Wilhelm Wundt (experimental psychology)
Rationalism alternatives: Immanuel Kant (categories of mind), Baruch Spinoza (mind as part of nature), Leibniz (perception and monadology)
Naturalism alternatives: William James (functionalism), Herbert Spencer (social Darwinism), G. Stanley Hall (developmental psychology)

Writing Each Section

How to Write Each Thinker Section

Each thinker section should answer the three assignment questions — who, what, and how it impacted psychology — without simply listing answers. Write it as a flowing argument, not a Q&A. Here is the structure to follow for each:

Structure for Each Thinker Section (~400–450 words each)

Repeat this pattern for all three traditions

Who~60 words

Introduce the thinker and their tradition. One to two sentences — name, era, and which school of thought they represent. Don’t spend half a page on biography. Example: “John Locke (1632–1704), a central figure in empiricist philosophy, argued in his Essay Concerning Human Understanding (1689) that all knowledge derives from sensory experience rather than innate ideas.”

What~180 words

Explain the specific contribution. Focus on the idea, not the person’s life events. What was the core claim? What did it replace or challenge? What was new about it? Use a primary source citation and at least one secondary scholarly source. Avoid: “Locke was a famous philosopher who contributed a lot to psychology.” Be specific about the idea.

Impact~180 words

Connect the contribution to the field of psychology — and to what comes next. How did this idea change how psychologists thought or worked? Name specific downstream effects. This section bridges Part 1 to Part 2 — end it with a sentence that points toward humanitarian reform.

✓ Strong Writing

“Locke’s tabula rasa directly challenged the idea that mental characteristics were fixed at birth — if the mind is shaped by experience, then the environments in which people with mental illness were kept became a legitimate target for reform (Schultz & Schultz, 2016). This argument was later deployed explicitly by Dorothea Dix in her 1843 Memorial to the Legislature of Massachusetts.”

✗ Weak Writing

“John Locke was an important empiricist philosopher. He believed that people learn from experience. This is important because it helped psychology. His ideas were used by many people and had a big impact on the field of psychology.”

Part Two — Humanitarian Reform

Connecting the Philosophy to Real-World Change

This is where students lose marks. The question asks you to examine how these intellectual changes led to reform — not just to note that reform happened. You need to trace the causal chain.

Tradition	Change in Research/Method	Change in Humanitarian Reform
Empiricism	Shifted psychological study toward direct observation and evidence — data about behavior and mental states replaced theological speculation	Reformers like Philippe Pinel and Dorothea Dix used observable evidence of suffering in asylums to argue for better conditions — the empiricist standard of evidence gave reform arguments their credibility
Rationalism	Made it intellectually respectable to study the mind as a rational object — applied reason to questions of mental illness, moving diagnoses from moral to medical frameworks	If mental illness was a rational, comprehensible phenomenon rather than spiritual failing, then rational treatment (not punishment) became the logical response — this framing underpinned moral treatment
Naturalism	Positioned behavior and mental life within biological science — psychology became a lab-based discipline with methods borrowed from natural science	Biological framing of mental illness removed moral culpability from patients — illness, not character weakness, needed treatment — which directly challenged punitive asylum practices

Key Reform Figures and Events to Reference

Your paper needs to name specific reforms — not just abstract trends. Here are the ones most relevant to this topic:

France, 1793

Philippe Pinel — Removing the Chains

Pinel removed chains from patients at Bicêtre asylum and introduced “moral treatment” — treating patients with dignity and routine rather than restraint. His approach directly reflected the rationalist argument that mental illness was a medical, treatable condition. This is often cited as the foundational act of humanitarian psychiatric reform and should appear in almost every paper on this topic.

England, 1796

William Tuke — The York Retreat

Tuke founded the York Retreat, an asylum based on humane principles — rest, work, and compassion over punishment. His model demonstrated in practice that treating patients as rational beings capable of improvement produced better outcomes than confinement. This aligns directly with both rationalist and empiricist frameworks.

USA, 1840s–1880s

Dorothea Dix — Legislative Advocacy

Dix campaigned across the United States documenting conditions in jails and poorhouses where the mentally ill were kept. Her approach was empiricist at its core — systematic observation, documented evidence, presented to lawmakers. Her reports directly led to state hospital legislation across more than 30 states. If you are writing about how empiricism led to reform, Dix is your clearest real-world example.

How to Answer the Three Reform Sub-Questions

Reform Section Structure (~500–600 words)

Cover all three sub-questions within one cohesive section

Research Changes~150 words

Describe the methodological shift. Pre-reform psychology relied on armchair philosophy and anecdote. Empiricism brought systematic observation. Naturalism brought experimentation and biological measurement. Rationalism brought structured reasoning and diagnostic classification. Briefly explain what research in psychology started to look like differently — and why that mattered.

Reform Changes~200 words

Describe specific changes in how society treated the mentally ill. Name Pinel, Tuke, Dix — and the concrete changes they produced: removal of physical restraints, state hospital legislation, the introduction of moral treatment. Be specific. “Conditions improved” is too vague. “Pinel’s introduction of moral treatment at Bicêtre in 1793 replaced chains and isolation with structured activity and physician interaction” is what your essay needs.

The Link~200 words

Directly argue how the three philosophical traditions enabled reform. This is the synthesis. Don’t just list thinkers and then list reforms separately — explain the mechanism. Locke’s blank-slate theory made environment relevant. Descartes’ rationalism made mental illness a medical problem. Darwin’s naturalism made it biological and treatable. Show how reformers drew on these frameworks to make their arguments for change.

Part Three — Modern Impact

How Humanitarian Reform Shapes Modern Mental Health Treatment

The final section of your paper needs to close the loop. The philosophical shifts of the 17th–19th centuries and the reform movement they enabled — how do those show up in 21st-century mental health care?

Don’t just write “today mental health treatment is better.” You need to name specific practices, policies, or frameworks that trace back to these reform roots.

Reform Legacy	Modern Expression
Moral treatment principles	Person-centered care, therapeutic environments, psychiatric rehabilitation — the idea that environment and relationship are therapeutic tools, not just medication
Deinstitutionalization movement	Community mental health centers, outpatient treatment, the Community Mental Health Act 1963 (USA) — moving care out of large institutions into community settings
Biological-medical model (from naturalism)	Diagnostic manuals (DSM-5, ICD-11), pharmacological treatment, neuroscience-based psychiatry — mental illness treated as a medical condition deserving treatment
Patient rights (from Locke’s political philosophy)	Informed consent, least restrictive environment principles, Mental Health Parity Act 2008 — legal protections for people with mental illness
Evidence-based practice (from empiricism)	Randomized controlled trials in psychiatry, clinical guidelines, the APA’s evidence-based practice framework — treatment based on observable data rather than tradition

💡

A strong closing argument

The best papers end with an argument about continuity and limitation. Yes, reform has happened — but acknowledge that the humanitarian challenges are not fully resolved. Disparities in mental health access, the ongoing debate about coercive treatment, and the gap between biological and social models of mental illness all trace back to unresolved tensions in the very philosophical traditions your paper covers. Naming this shows genuine critical thinking.

Quality Control

Common Mistakes — And How to Fix Each One

❌ Common Mistake	Why It Loses Marks	✓ The Fix
Describing what a thinker believed without applying it to psychology or reform	Description earns pass-level marks at best; application earns upper grades	After every claim about a thinker, write a sentence beginning “In the context of psychology, this meant that…” — force yourself to make the connection explicit
Writing “these ideas led to reform” without naming specific reformers or events	Vague causal claims signal that the student doesn’t actually know the history	Name Pinel (1793), Tuke (1796), Dix (1843) — and the specific changes they produced
Treating the three traditions as completely separate and never connecting them	The assignment asks how they collectively led to reform — if you write three isolated mini-papers, you miss the synthesis entirely	In your reform section, write at least one paragraph that explicitly integrates all three traditions into a single argument
Spending 80% of the paper on Part 1 and rushing Part 2	The reform and modern impact sections are often worth as many marks as the thinker sections	Allocate word count deliberately before you start writing — the outline table above gives you a proportional breakdown
Ending the paper with “in conclusion, these philosophers changed psychology”	Summarizing rather than synthesizing loses marks in the conclusion	End with a specific claim about what the historical arc means — e.g., the tension between biological and social models of mental illness that these traditions set up is still unresolved today
Not formatting the title page correctly	Formatting errors signal inattention — costs easy marks	Check APA 7th student title page requirements: title in bold, centered, followed by name, institution, course code, instructor, date — all double-spaced

Common Questions

FAQs: What Students Ask Most About This Paper

Who should I choose to represent empiricism in a psychology history paper?

John Locke is the strongest choice for most versions of this assignment. His tabula rasa concept directly challenged the idea that mental characteristics were fixed or inherited, and his political philosophy (particularly on individual rights and the role of government) directly influenced reformers like Dorothea Dix. If your course specifically covers experimental psychology, Wilhelm Wundt is a strong alternative — he brought empiricist methods directly into a laboratory setting and is often credited as founding modern experimental psychology in 1879.

How does Descartes connect to psychology if he was a philosopher?

This is exactly the point your paper needs to make. Descartes didn’t do psychology in the modern sense — but his mind-body dualism created the philosophical architecture that made a science of the mind possible. By arguing that the mind was a distinct entity that could be studied through reason, he moved mental phenomena out of the exclusive domain of theology and into the realm of rational inquiry. That shift is what eventually made psychiatry — the medical treatment of mental illness — intellectually legitimate. The argument in your paper is that rationalism didn’t directly create psychology, but it created the conditions under which psychology could exist.

What specific changes in research methods should I describe?

The shift from philosophical speculation to empirical observation is the core methodological change. Before the influence of empiricism and naturalism, knowledge about the mind came primarily from armchair reasoning, religious interpretation, and anecdote. The empiricist tradition brought the idea that knowledge must be grounded in observable, repeatable experience — which eventually produced controlled experiments, systematic case studies, and structured observation. Naturalism added biological measurement and comparative methods. Rationalism contributed systematic classification — the idea that mental states could be categorized and described logically. Together, these gave psychology its methodological toolkit.

Do I need to cover all three traditions in my reform and modern impact sections?

Yes — the assignment explicitly asks how the contributions from empiricism, rationalism, and naturalism led to humanitarian reform, and how humanitarian reform impacted modern mental health treatment. You don’t need to give each tradition equal space in those sections, but all three should be referenced. The easiest approach is to write the reform section as an integrated argument that draws on all three rather than covering each tradition in a separate paragraph.

Final Thoughts

The Through-Line Your Paper Needs to Argue

The real argument of this paper is not that three philosophers existed and reform happened. It’s that a specific kind of intellectual shift — moving the explanation of human behavior and mental illness from the supernatural to the empirical, from moral to medical, from fixed to malleable — created the conditions under which treating the mentally ill with humanity became not just morally desirable but intellectually defensible.

Pinel didn’t remove chains because he was a kind person. He removed them because the rationalist and empiricist traditions had given him a framework in which doing so made scientific sense. Dix didn’t campaign for state hospitals because she found asylum conditions upsetting. She campaigned using documented evidence because the empiricist standard of proof had become the standard for public argument.

That’s the paper. The thinkers set up the logic. The reformers applied it. The modern mental health system — with all its advances and remaining failures — is still working out the implications.
