Tabula rasa in the context of "Nature versus nurture debate"

In the philosophy of mind, innatism is the view that the mind is born with already-formed ideas, knowledge, and beliefs. The opposing doctrine, that the mind is a tabula rasa (blank slate) at birth and all knowledge is gained from experience and the senses, is called empiricism.

An Essay Concerning Human Understanding is a work by John Locke concerning the foundation of human knowledge and understanding. It first appeared in 1689 (although dated 1690) with the printed title An Essay Concerning Humane Understanding. He describes the mind at birth as a blank slate (tabula rasa, although he did not use those actual words) filled later through experience. The essay was one of the principal sources of empiricism in modern philosophy, and influenced many enlightenment philosophers, such as David Hume and George Berkeley.

Book I of the Essay is Locke's attempt to refute the rationalist notion of innate ideas. Book II sets out Locke's theory of ideas, including his distinction between passively acquired simple ideas—such as "red", "sweet", "round"—and actively built complex ideas, such as numbers, causes and effects, abstract ideas, ideas of substances, identity, and diversity. Locke also distinguishes between the truly existing primary qualities of bodies, like shape, motion and the arrangement of minute particles, and the secondary qualities that are "powers to produce various sensations in us" such as "red" and "sweet." These secondary qualities, Locke claims, are dependent on the primary qualities. He also offers a theory of personal identity, offering a largely psychological criterion. Book III is concerned with language, and Book IV with knowledge, including intuition, mathematics, moral philosophy, natural philosophy ("science"), faith, and opinion.

A wax tablet is a tablet made of wood and covered with a layer of wax, often linked loosely to a cover tablet, as a "double-leaved" diptych. It was used as a reusable and portable writing surface in antiquity and throughout the Middle Ages. Cicero's letters make passing reference to the use of cerae, and some examples of wax-tablets have been preserved in waterlogged deposits in the Roman fort at Vindolanda on Hadrian's Wall. Medieval wax tablet books are on display in several European museums.

Writing on the wax surface was performed with a pointed instrument, a stylus. A straight-edged spatula-like implement (often placed on the opposite end of the stylus tip) would be used as an eraser. The modern expression of "a clean slate" equates to the Latin expression "tabula rasa".

In psychology and ethology, imprinting is a relatively rapid learning process that occurs during a particular developmental phase of life and leads to corresponding behavioural adaptations. The term originally was used to describe situations in which an animal internalises (learns) the characteristics of a perceived object, for example of a dangerous predator or a sweet fruit. Sigmund Freud, the founder of psychoanalysis, provided the first scientific explanation of how imprinting really works, developing the thesis that our brain can store experiences in its neural network through "a permanent change after an event" – one of the main functions of the long-term memory, which he called superego. Shaped by social experiences during childhood, this instance is connected to the ego (consciousness) which is necessary for controlling behaviour in order to satisfy a series of innate needs. Ultimately the imprinted superego performs the function of conscience, which makes aware of two types of feelings: warnings not to repeat wrong decisions; and anticipation of the repeated experience of satisfaction.

Even in ancient times, philosophers pondered the material properties that would be necessary for the function of ‘remembering’ and the learning process as such. To illustrate this, they imagined a kind of writing tablet in the brain, which was like soft clay and remained blank until an experience was mechanically ‘imprinted’ onto it.

Some nativists believe that specific beliefs or preferences are "hard-wired". For example, one might argue that some moral intuitions are innate or that color preferences are innate. A less established argument is that nature supplies the human mind with specialized learning devices. This latter view differs from empiricism only to the extent that the algorithms that translate experience into information may be more complex and specialized in nativist theories than in empiricist theories. However, empiricists largely remain open to the nature of learning algorithms and are by no means restricted to the historical associationist mechanisms of behaviorism.
