精一杯生きる seiippai ikiru Live Life
精一杯生きる (seiippai ikiru), live with all you have, is plain modern Japanese, a sentence the language makes. Its adverb 精一杯 is first cited from a puppet play of 1766, and the National Diet Library's collection shows the phrase common only after 1950. This study follows its printed life in that collection, from a book of poems of 1923 to 5,757 items.
Abstract
精一杯生きる, seiippai ikiru, live with all you have, is plain modern Japanese: the adverb 精一杯, to the limit of one's strength, first cited from a puppet play of 1766, set before 生きる, to live, in its dictionary form. It has no source text; it is a sentence the language makes, and its printed life is a twentieth-century one. With the particle に it is in a book of poems of 1923 and in forty-one items of the National Diet Library's digital collection before 1946; in exactly this form it is in a literary magazine of 1937, and it becomes common only after 1950. The Library's collection holds 5,757 items that print it.
Overview
The sense. Plain spoken Japanese, the verb in the dictionary form, which is how a resolution is written. 精一杯生きる, live with all you have, is grammatical and reads at once, and a writer of 1944 sets it beside the word for resolve.
The words. 生きる ikiru, to live. デジタル大辞泉: 人間・動物などが、生命があり活動できる状態にある。生命を保つ。生存する, to be in the state of having life and being able to act; to keep life; to exist, then to make a living, then to live in or for something, 研究一筋に生きる. It is the modern form of an old verb, いく. 精選版日本国語大辞典 cites it from the 宇治拾遺物語 of about 1221, この里の人々、とく逃げのきて命いきよ, people of this village, flee quickly and live, where いきよ is the classical form [1]; the verb itself is older, and the dictionary cites いく in its first conjugation from the 万葉集 of the late eighth century, 伊家るしるしあり, there is proof in being alive [2]. 精一杯 seiippai: 持っている力のすべてを出すこと。力のかぎり。できるかぎり, putting out all the strength one has; to the limit of one's strength; as much as one can, an adverb, first cited from a 1766 puppet play, 本朝二十四孝; the dictionary's second citation, from 仮名垣魯文's 安愚楽鍋 of 1871–72, spells it 性一ぱい [3].
The text in English. Live covers 生きる exactly [4] [5]; the difference is in what each language does without a subject. An English live with no subject is an imperative, and 精一杯生きる is not: the Japanese dictionary form is a statement of what one does or intends, which is why the phrase reads as a resolution rather than a command, and why a rendering should not put an exclamation mark after it. The nearest English saying, live life to the fullest, is dated by The Dictionary of Modern Proverbs to 1934, in a sociologist's summary of what college students believed: Life is short and after death we are dust, so why not live life to the fullest [6]. The two do not cover the same ground. Kenkyusha's New Collegiate Japanese-English Dictionary gives 精一杯 as as hard as possible, to the best of one's ability, with all one's might: strength spent. It puts live life to the full(est) under 充実, fullness, as 最高に充実した生活を送る [7]. The English saying asks for a full life; 精一杯生きる asks for all one's strength.
The historical record
What is not a source. No Japanese text stands behind it. The phrase has no author, no classic and no first speaker; it is what the adverb and the verb say when they are set side by side.
1923. With に, in a poem. 高橋元吉's book of poems 耽視 closes a poem on a soul lost in the dark, 或物語の記憶の斷片, with いつも內から精一杯に生きゆく魂 / その成果の打算によらず, a soul that always lives from within with all its strength, / not by any reckoning of its gains [8]. It is the oldest item the National Diet Library's full-text index returns for 精一杯に生き.
1937. In exactly this form. 中野秀人's essay 砧村畫帳, in the December 1937 issue of 三田文學: 實際は精一杯生きることによつて、何時かは清算され得るその希望を持つても宜いといふことを學んだ, I learned that, in fact, by living with all I have, I might hope that some day it could be settled. The issue is open only inside the Library, so the sentence is quoted from the search excerpt, where one character is unread and is supplied here from the sense [9]. It is the oldest item the index returns for 精一杯生きる.
1944 and 1946. In books. 亀井勝一郎's 人生論 writes of the sick: また不治を宣告されて、はじめて精一杯生きようと決心した人もある, and there are some who, told that they cannot be cured, resolve for the first time to live with all they have [10]. 島木健作's novel 礎 has both forms on one page: 靑年期には靑年期にふさはしく、壯年期にはまたそれにふさはしく精一杯に生きることが何より大切だ, what matters most is to live with all you have, as befits youth in youth and as befits the prime of life in its prime, and, of a young man, いつの時期をも精一杯生きてゆく人, a man who will live every season of his life with all he has [11].
Before and after 1950. Before the war the phrase was written with に. The full-text index returns forty-one items printing 精一杯に生き before 1946, some of them reprints of one text, and one printing 精一杯生きる, the 1937 essay. Without に it grows after 1950: the index holds 5,757 items that print 精一杯生きる, the hundredth of them from 1966 and the three-hundredth from 1974, and the first of them are diaries and memoirs, books on teaching, film reviews and weekly magazines [12]. The kana spellings come later still: 精一ぱい生き from 1942, 精いっぱい生き from 1951. The public-domain books the Library's full-text search reads [13] never print it in this form; they carry it with に, or conjugated, as the witnesses above do.
Today. What a rendering must keep is the verb's mood: a resolution, not an order.
A reading
精一杯生きる is honest modern Japanese: an adverb of a 1766 puppet play set before the verb of living, a resolution in the dictionary form. It has no author. A poet of 1923 and an essayist of 1937 reached for it when they meant to live by strength rather than by reckoning, and a writer of 1944 put it beside resolve. The prewar pages mostly wrote it with に; the form on the scroll, without the particle, is the one the postwar decades made common. What it says, it says at once.
