Word: self Part of Speech: noun Etymology: From Middle English salve, self, silf, from Old English self, seolf, sylf, from Proto-Germanic *selbaz, from Proto-Indo-European *selbʰ- (“one's own”). Cognates Cognates with Saterland Frisian sälven, säärm, sääuwen (“oneself”), West Frisian sels (“oneself”), Bavarian söbe (“identical, same”), söber (“self”), Dutch zelf (“myself, oneself”), German selber (“self”), selbst (“by oneself”), Luxembourgish selwer (“self”), Yiddish זעלב (zelb, “same”), Danish selv (“self”), Elfdalian siuov (“self”), Faroese sjálvur (“self”), Icelandic sjálfur (“self”), Norwegian Bokmål selv, Norwegian Nynorsk sjølv, Swedish själv (“self”), Gothic 𐍃𐌹𐌻𐌱𐌰 (silba, “self”). Pronunciation: /ˈsɛlf/, /ˈsɛf/, /ˈsɛl/ 1. One individual's personality, character, demeanor, or disposition. Example: She remained her usual cheerful self despite recent setbacks Example: John Locke argued that the mind is not like a furnished flat, prestocked before occupation with innate ideas, but like a home put together piecemeal from mental acquisitions picked up bit by bit. The self is thus the bit-by-bit product of experience and education: we are what we become - or, in Wordworth's later phrase, the child is the father of the man. Particular parents, surroundings and stimuli produce individuated selves. Identity is thus unique because contingent, the cumulative product of ceaseless occurrences. 2. The subject of one's own experience of phenomena: perception, emotions, thoughts. Example: Portia: To these injunctions every one doth swear That comes to hazard for my worthless self. Example: Thanks to that penny he had just spent so recklessly [on a newspaper] he would pass a happy hour, taken, for once, out of his anxious, despondent, miserable self. It irritated him shrewdly to know that these moments of respite from carking care would not be shared with his poor wife, with careworn, troubled Ellen. 3. An individual person as the object of the person's own reflective consciousness (plural selves). Example: The self, the I, is recognized in every act of intelligence as the subject to which that act belongs. It is I that perceive, I that imagine, I that remember, I that attend, I that compare, I that feel, I that will, I that am conscious. Example: The preposterous altruism too![…]Resist not evil. It is an insane immolation of self—as bad intrinsically as fakirs stabbing themselves or anchorites warping their spines in caves scarcely large enough for a fair-sized dog. 4. Self-interest or personal advantage. 5. A seedling produced by self-pollination (plural selfs). 6. A flower having its colour uniform as opposed to variegated. 7. Any molecule, cell, or tissue of an organism's own (belonging to the self), as opposed to a foreign (nonself) molecule, cell, or tissue (for example, infective, allogenic, or xenogenic). Example: Similarity profiles between helper T cell epitopes (of self or microbial antigens and allergens) and human or microbial SWISSPROT collections were produced. For each antigen, both collections yielded largely overlapping profiles, demonstrating that self-nonself discrimination does not rely on qualitative features that distinguish human from microbial peptides. [...] Epitopes (on self and nonself antigens) can cross-stimulate T cells at increasing potency as their similarity with nonself augments. Example: In plants, the ability to recognize self from nonself plays an important role in fertilization, because self-fertilization will result in less diverse offspring than fertilization with pollen from another individual.
