Explanation
Identity is attributed or claimed sameness and continuity across difference and change. For persons, groups, texts, and linguistic forms, the question of what counts as the same despite alteration is answered differently. A name, memory, institutional recognition, or structural pattern may carry continuity without preserving every property unchanged. Identity is therefore neither mere resemblance nor rigid substance. It also emerges through names, narratives, and social negotiations that enable belonging and draw boundaries. The concept leads from the simple formula “A is A” toward the criteria of its validity: who recognises sameness, which differences remain compatible with it, and when does the claim of one identity conceal rupture or plurality?
Movement of thought
1. An object, person, or group first appears at different times or in different representations with perceptible changes. 2. Certain features, histories, names, or relations are selected and foregrounded as carriers of continuing sameness. 3. Social and linguistic recognition stabilises continuity while other differences are classified as change within the same entity. 4. A counter-test examines criteria, power, and excluded variants and asks when asserted continuity conceals an actual rupture. 5. Identity returns as an open bond between sameness and transformation, capable of preserving connection without erasing difference.
Scientific use case
Philosophy, sociolinguistics, discourse analysis, and textual criticism specify criteria of sameness, self- and external ascription, and temporal continuity. Variant cases test which differences a category permits.
Example
A multilingual person uses different forms of expression in different settings yet recognises all those voices within one biography; continuity does not require linguistic uniformity.
Counterexample
Two texts use the same typeface but have different authors, content, and transmission. A shared property alone does not establish that the texts are identical.
Distinction
Distinguish identity from numerical equality, qualitative resemblance, identification as a process, belonging, and immutable essence. Criteria and authorities of recognition must be specified for each domain.
Effect on thought and perception
Concepts of identity create continuity, recognition, and agency but may normalise diversity, harden boundaries, or narrate historical rupture as an unchanged unity.
Resonance
Different voices and times answer the question of the same self; identity carries when their connection can absorb change without surrendering memory.

Historical background
The Cours asks what makes a linguistic unit the same across different occurrences by comparing kinds of sameness outside language. Successive departures of a scheduled train can count as the same train despite changes of vehicle and staff. A rebuilt street can retain its identity, whereas identifying a stolen coat involves the material object in another way. These comparisons do not prove that personal or social identity is reducible to linguistic value. They establish that the relevant criterion of sameness depends on the question and the system of relations being considered. Historically, this is a structural problem in a linguistic exposition published in 1916, not the beginning of philosophical inquiry into identity. For the Atlas, the productive movement is from asking whether two appearances look alike to specifying what must persist for them to count as instances of the same unit. The source helps discipline a broad profile, but other senses, the English word’s history and later debates require separate evidence rather than an unrestricted extension of the train analogy.
How conceptual history changes the analysis
Compare two occurrences: what persists—material, function, location or relationship? Specify the criterion before claiming sameness or identity.
