Heart \Heart\, n. [OE. harte, herte, heorte, AS. heorte; akin to
   OS. herta, OFies. hirte, D. hart, OHG. herza, G. herz, Icel.
   hjarta, Sw. hjerta, Goth. ha['i]rt?, Lith. szirdis, Russ.
   serdtse, Ir. cridhe, L. cor, Gr. ?, ? ????. Cf. Accord,
   Discord, Cordial, 4th Core, Courage.]
   1. (Anat.) A hollow, muscular organ, which, by contracting
      rhythmically, keeps up the circulation of the blood.

            Why does my blood thus muster to my heart! --Shak.

   Note: In adult mammals and birds, the heart is
         four-chambered, the right auricle and ventricle being
         completely separated from the left auricle and
         ventricle; and the blood flows from the systematic
         veins to the right auricle, thence to the right
         ventricle, from which it is forced to the lungs, then
         returned to the left auricle, thence passes to the left
         ventricle, from which it is driven into the systematic
         arteries. See Illust. under Aorta. In fishes there
         are but one auricle and one ventricle, the blood being
         pumped from the ventricle through the gills to the
         system, and thence returned to the auricle. In most
         amphibians and reptiles, the separation of the auricles
         is partial or complete, and in reptiles the ventricles
         also are separated more or less completely. The
         so-called lymph hearts, found in many amphibians,
         reptiles, and birds, are contractile sacs, which pump
         the lymph into the veins.

   2. The seat of the affections or sensibilities, collectively
      or separately, as love, hate, joy, grief, courage, and the
      like; rarely, the seat of the understanding or will; --
      usually in a good sense, when no epithet is expressed; the
      better or lovelier part of our nature; the spring of all
      our actions and purposes; the seat of moral life and
      character; the moral affections and character itself; the
      individual disposition and character; as, a good, tender,
      loving, bad, hard, or selfish heart.

            Hearts are dust, hearts' loves remain. --Emerson.

   3. The nearest the middle or center; the part most hidden and
      within; the inmost or most essential part of any body or
      system; the source of life and motion in any organization;
      the chief or vital portion; the center of activity, or of
      energetic or efficient action; as, the heart of a country,
      of a tree, etc.

            Exploits done in the heart of France. --Shak.

            Peace subsisting at the heart Of endless agitation.
                                                  --Wordsworth.

   4. Courage; courageous purpose; spirit.

            Eve, recovering heart, replied.       --Milton.

                                                  Temple.

   5. Vigorous and efficient activity; power of fertile
      production; condition of the soil, whether good or bad.

            That the spent earth may gather heart again.
                                                  --Dryden.

   6. That which resembles a heart in shape; especially, a
      roundish or oval figure or object having an obtuse point
      at one end, and at the other a corresponding indentation,
      -- used as a symbol or representative of the heart.

   7. One of a series of playing cards, distinguished by the
      figure or figures of a heart; as, hearts are trumps.

   8. Vital part; secret meaning; real intention.

            And then show you the heart of my message. --Shak.

   9. A term of affectionate or kindly and familiar address. ``I
      speak to thee, my heart.'' --Shak.

   Note: Heart is used in many compounds, the most of which need
         no special explanation; as, heart-appalling,
         heart-breaking, heart-cheering, heart-chilled,

HEART, n.  An automatic, muscular blood-pump.  Figuratively, this
useful organ is said to be the esat of emotions and sentiments -- a
very pretty fancy which, however, is nothing but a survival of a once
universal belief.  It is now known that the sentiments and emotions
reside in the stomach, being evolved from food by chemical action of
the gastric fluid.  The exact process by which a beefsteak becomes a
feeling -- tender or not, according to the age of the animal from
which it was cut; the successive stages of elaboration through which a
caviar sandwich is transmuted to a quaint fancy and reappears as a
pungent epigram; the marvelous functional methods of converting a
hard-boiled egg into religious contrition, or a cream-puff into a sigh
of sensibility -- these things have been patiently ascertained by M.
Pasteur, and by him expounded with convincing lucidity.  (See, also,
my monograph, _The Essential Identity of the Spiritual Affections and
Certain Intestinal Gases Freed in Digestion_ -- 4to, 687 pp.)  In a
scientific work entitled, I believe, _Delectatio Demonorum_ (John
Camden Hotton, London, 1873) this view of the sentiments receives a
striking illustration; and for further light consult Professor Dam's
famous treatise on _Love as a Product of Alimentary Maceration_.

Heart
   According to the Bible, the heart is the centre not only of
   spiritual activity, but of all the operations of human life.
   "Heart" and "soul" are often used interchangeably (Deut. 6:5;
   26:16; comp. Matt. 22:37; Mark 12:30, 33), but this is not
   generally the case.
   
     The heart is the "home of the personal life," and hence a man
   is designated, according to his heart, wise (1 Kings 3:12,
   etc.), pure (Ps. 24:4; Matt. 5:8, etc.), upright and righteous
   (Gen. 20:5, 6; Ps. 11:2; 78:72), pious and good (Luke 8:15),
   etc. In these and such passages the word "soul" could not be
   substituted for "heart."
   
     The heart is also the seat of the conscience (Rom. 2:15). It
   is naturally wicked (Gen. 8:21), and hence it contaminates the
   whole life and character (Matt. 12:34; 15:18; comp. Eccl. 8:11;
   Ps. 73:7). Hence the heart must be changed, regenerated (Ezek.
   36:26; 11:19; Ps. 51:10-14), before a man can willingly obey
   God.
   
     The process of salvation begins in the heart by the believing
   reception of the testimony of God, while the rejection of that
   testimony hardens the heart (Ps. 95:8; Prov. 28:14; 2 Chr.
   36:13). "Hardness of heart evidences itself by light views of
   sin; partial acknowledgment and confession of it; pride and
   conceit; ingratitude; unconcern about the word and ordinances of
   God; inattention to divine providences; stifling convictions of
   conscience; shunning reproof; presumption, and general ignorance
   of divine things."
