Self-reflection is the ability to witness and evaluate one's own cognitive, emotional, and behavioural processes. In psychology, other terms used for this self-observation include "reflective awareness" and "reflective consciousness", which originate from the work of William James. Self-reflection depends upon a range of functions, including introspection and metacognition, which develop from infancy through adolescence, affecting how individuals interact with others, and make decisions. Self-reflection is related to the philosophy of consciousness, the topic of awareness, and the philosophy of mind. The concept of self-reflection is ancient. More than 3,000 years ago, "Know thyself" was the first of three Delphic maxims inscribed in the forecourt of the Temple of Apollo at Delphi. It is also considered a form of thought that generates new meaning and an opportunity to engage with what seemingly appears incongruous.
History
Early writings Notions about the status of humanity may be revealed by the etymology of ancient words for humans. Latin homo (PIE *dʰǵʰm̥mō) means "of the earth, earthling", probably in opposition to "celestial" beings. Greek ἂνθρωπος (mycenaean *Anthropos) means "low-eyed", again probably contrasting with a divine perspective. From the third-millennium Old Kingdom of Egypt, belief in an eternal afterlife of the human ka is documented along with the notion that the actions of a person would be assessed to determine the quality of that existence. A claim of dominance of humanity alongside radical pessimism because of the frailty and brevity of human life is asserted in the Hebrew Bible Genesis 1:28, where dominion of humans is promised, but contrarily, King Solomon who is the alleged author of Ecclesiastes according to rabbinic tradition, bewails the vanity of all human effort.
Classical antiquity Protagoras made the famous claim that humans are "the measure of all things; of what is, that it is; of what is not, that it is not". Socrates advocated the ancient adage for all humans to "Know thyself", and gave the (doubtlessly tongue-in-cheek) definition of humans as, "featherless bipeds" (Plato, Politicus). Aristotle described humans as the "communal animal" (ζῶον πολιτικόν), i.e., emphasizing society-building as a central trait of human nature, and being a "thought bearer animal" (ζῶον λόγον ἔχον, animal rationale) a term that also may have inspired the species taxonomy, Homo sapiens.
Middle Ages The dominant world-view of medieval Europe, as directed by the Catholic Church, was that human existence is essentially good and created in "original grace", but because of concupiscence, is marred by sin, and that its aim should be to focus on a beatific vision after death. The term "original grace" is not a phrase directly derived by the Bible, but is used because it reflects the Catholic Church's interpretation of humanity's initial state before the Fall. According to St. Augustine, the Fall corrupted this "original grace" and therefore the nature of man. The thirteenth century pope Innocent III wrote about the essential misery of earthly existence in his "On the misery of the human condition"—a view that was disputed by, for example, Giannozzo Manetti in his treatise "On human dignity".
Renaissance
A famous quote of Shakespeare's Hamlet (II, ii, 115–117), expresses the contrast of human physical beauty, intellectual faculty, and ephemeral nature:
What a piece of work is a man! How noble in reason! how infinite in faculties! in form and moving, how express and admirable! in action how like an angel! in apprehension, how like a god! the beauty of the world! the paragon of animals! And yet, to me, what is this quintessence of dust?
René Descartes famously and succinctly proposed: Cogito ergo sum (French: "Je pense donc je suis"; English: "I think, therefore I am"), not an assessment of humanity, but certainly reflecting a capacity for reasoning as a characteristic of humans, that potentially, could include individual self-reflection.
Modern era The Enlightenment was driven by a renewed conviction, that, in the words of Immanuel Kant, "Man is distinguished above all animals by his self-consciousness, by which he is a 'rational animal'." In conscious opposition to this tradition during the nineteenth century, Karl Marx defined humans as a "labouring animal" (animal laborans). In the early twentieth century, Sigmund Freud dealt a serious blow to positivism by postulating that, to a large part, human behaviour is controlled by the unconscious mind. Freud describes the unconscious mind as the part of the mind containing any repressed images or thoughts too taboo for societal norms. He viewed this part of the mind as essential to the individual as they are restrained primitive impulses and desires. Joseph Conrad uses the analogy of chemistry to describe how the tiniest idea can stimulate a person during reflection like a "little drop precipitating the process of crystallization in a test tube containing a colourless solution".
Mandatory or advisory periods for reflection are built into some regulatory requirements, for example changes to divorce law in England and Wales adopted in 2022 prescribe a 20-week period of reflection before certain proceedings are concluded, and the European Union's Mortgage Credit Directive allows for a seven-day period of reflection before a mortgage offer needs to be accepted.
