Tabula Rasa
Blank slate — Locke's view that we're born without innate ideas
Tabula rasa (Latin: "blank slate") is the view that humans are born without innate ideas or knowledge — all knowledge comes from experience. Most associated with John Locke (1689). Empiricist response to rationalist innate ideas (Plato, Descartes). All ideas: from sensation (external world) and reflection (mental processes). Implications: nurture over nature, equality of human nature, education's importance. Contemporary view: rejected as too extreme — humans have innate cognitive structures (Chomsky's universal grammar, evolutionary psychology). But: empiricist insight on experience's role remains influential.

Why tabula rasa matters
- Epistemology. Foundation of empiricism.
- Education. Optimism about teaching.
- Equality. Opposed to claims of innate inequality.
- Cognitive science. Influences current debate.
- Politics. Implications for social engineering.
- Psychology. Nature vs nurture.
- Philosophy. Foundation of empiricism.
Common misconceptions
- Settled view. Modern science rejects strict version.
- Locke endorses social engineering. Argues for individual liberty too.
- Blank means nothing innate. Locke acknowledges innate capacities for learning.
- Modern science endorses innate everything. Combines innate + experience.
- Cultural determinism follows. Locke didn't fully accept this.
- Locke endorsed all later interpretations. Specific views.
Frequently asked questions
What's tabula rasa?
View that mind starts blank; all knowledge from experience. No innate ideas, knowledge, principles. We're born with capacity to receive and organize experience, but content comes from experience. Locke's empiricism. Opposed: rationalist innate ideas. Implication: experience and education shape who we become.
What was Locke's argument?
John Locke (1689). "Essay Concerning Human Understanding." Argued: no innate principles. (1) "Universal" principles aren't really universal — children, "savages" don't have them. (2) Where would innate ideas come from? Why not inscribed in animals? (3) Specific examples: number, mathematics, ethics — all from experience and reflection. Argued at length against Cartesian innate ideas.
What are sensation and reflection?
Locke's two sources of ideas. (1) Sensation: ideas from external senses (see colors, hear sounds, etc.). (2) Reflection: ideas from observing one's own mental operations (think about thinking, observe pleasure, etc.). All ideas derived from these two sources. Complex ideas: combinations of simple ideas. Foundation of empiricist epistemology.
What's Chomsky's challenge?
Noam Chomsky (1959, 1965). Children acquire language too quickly and creatively to be just learned. Universal grammar: innate cognitive structure for language. Suggests: innate cognitive equipment, not blank slate. Modern cognitive science: agrees with Chomsky; humans have many innate predispositions (face recognition, intuitive physics, theory of mind, etc.).
What's evolutionary psychology's view?
Modern view: evolution shaped human cognitive architecture. Innate biases, predispositions, modules for specific tasks. Examples: incest avoidance, basic emotional responses, theory of mind. Pinker, Cosmides, Tooby. Different from Locke's blank slate. Doesn't deny experience's role; claims experience interacts with innate structures.
What about culture vs nature?
Major debate. Tabula rasa view: culture/environment determines almost everything. Modern view: nature provides framework; culture fills in. Both interact. Most differences between humans across cultures: cultural. But specific human nature: shared innate biology. "Nature vs nurture" oversimplified — both important, interacting.
What are the implications?
Different views imply different conclusions. Tabula rasa: education paramount; people very malleable; environment shapes character. Modern: innate predispositions matter; education works with these; people's nature constrains. For policy: less optimistic about social engineering. For ethics: respect for individual nature. Both: education important; differing emphasis.
