      助記提示


      1. posit- + -ive.
      2. etymologically means 'placed down, laid down', hence 'emphatically asserted'.
      3. from Latin, meaning 'settled by agreement'.
      4. => dealing only with facts, absolute, expressed without qualification, confident in opinion, concentrating on what is constructive and good.
      5. placed down, laid down: 著實(shí)、敲定、確定下來(lái),或者主觀、武斷地確定下來(lái),或者主觀地認(rèn)為確定下來(lái)了。
      6. 即:由字面、詞源含義(placed down, laid down)引申表示為:主觀心理的、客觀實(shí)際的放下來(lái)了、確定下來(lái)的、定下來(lái)了。
      7. 主觀心理的其實(shí)就是認(rèn)為確定下來(lái)了、定下來(lái)了,由此引申為:確信的,自信的,有把握的;進(jìn)一步引申為:懷有希望的,往好的方向走的;進(jìn)一步引申為:積極的(而非消極的,就是一種樂(lè)觀的、正面的認(rèn)為確定下來(lái)了);由此進(jìn)一步引申為更寬泛的、廣義的、各行業(yè)的“積極的”含義:陽(yáng)性的,正數(shù)的,剛性的,向性的,趨性的等含義。
      8. 該詞的反義詞為:negative.

      英文詞源


      positive (adj.)
      early 14c., originally a legal term meaning "formally laid down," from Old French positif (13c.) and directly from Latin positivus "settled by agreement, positive" (opposed to naturalis "natural"), from positus, past participle of ponere "put, place" (see position (n.)).

      Sense of "absolute" is from mid-15c. Meaning in philosophy of "dealing only with facts" is from 1590s. Sense broadened to "expressed without qualification" (1590s), then "confident in opinion" (1660s); mathematical use is from 1704; in electricity, 1755. Psychological sense of "concentrating on what is constructive and good" is recorded from 1916.
      positive (n.)
      1520s, from positive (adj.).
