AGNOS'TICISM (Ok. ajTuurof, aynostos, unknown. unkno«al)le, ignorant). A word coined by Professor Hu.vley to express the doctrine that man from his very nature is incapable of forming trustworthy conclusions concerning ultimate reality. The doctrine is by no means new. It is essentially one with the view of Protagoras (q.v.). that the individual man is the measure of the universe, and with tlie view of the Cireek skeptics from Pyrrho onward. (See .-l-^NE- SIDEMUS.) Among English-speaking philoso- phers H. Speneer (q.v. ) is the best known agnos- tic. The tenability of the agnostic position de- pends on the justifiability of the dualistic assumption that reality is independent of mind. It argues that knowledge is the result of a men- tal process which claims to represent an external reality; that to know this claim to be valid is possible only after a comparison of the repre- sentation with the original ; but that the original is, ex hyp., not an object of knowledge; hence, that no comparison is possible for the knower. Knowledge of re.ality is thus a huge undemon- strable assumption. For a criticism of agnos- ticism see Knowj.f.dge. Tiieouy of; Absolute; Dlali.sm, and .Vppearance.

AGNOS'TUS ((4k. uyvuamr, n.f/»if;s(o.s, un- known I. A characteristic Cambrian genus of blind trilobilcs distinguished by their small size, the elliptical form of the dorsal shield or cara- pace, the close resemblance of the head-shield (cephalon) and tail-shield (pygidium), and the presence of only two segments in the thorax. This genus, com|)rising over 1.50 species, is abun- dantly rcpre>enlid in the Cambrian formations of Scandinavia, Bohemia. Creat Britain. Spain, and North America: indeed, certain kinds of Cambrian shales arc filled with the detached frag- ments of tile discarded moults of these crusta- ceans. A few species are, in northern Europe, known from the lowermost Ordoician beds. allied genus, also characteristic of the C:unbrian formations, is Microdiseus, with four thoracic segments, which seems to be a somewhat earlier form than Agnostus. and may perhaps bi> in a certain sense the ancestral form from which Agnostus was evolved. For illustration, see Tril- ouiTA. See also articles on TitiLoiiiTA ; Cam- IIKIAN SYSTESf.

AG'NUS DEI (Lat.. Lamb of God). One of the titles of Christ (John i. 2!t) ; also the name given to a certain prayer used in the Roman Catholic service of mass. The litanies generally conclude with the same prayer: "O Lamb of God. that takest away the sins of the world, have mercy upon us." The figure of a lamb bearing a cross, stamped U]>on an oval of wax, silver, or gold, is also styled an .gnus Dei. Such medals have been consecrated by the popes since the fourteenth century, and are generally <listributed among the faithful on the first Sun- day after Easter. In the ancient Church candi- dates for baptism received similar medals of wax and wore them as objects of devotion. In the Greek Church the cloth which covers the cup in the communion service bears the image of a lamb, and is styled the Agnus Dei.

AGONIC LINES ("lines without angles," from (ik. It, </, priv. + yuviu, gijnia, angle). Imaginary lines on the surface of the earth such that at each point through which one passes the magnetic declination is zero; that is, at such a point a magnetic compass needle lies in the geographical meridian, and hence points in a "true" north and south direction. There are two agonic lines at the present time ( 1IK)2 ). One is a closed curve passing across Hudson's Bay, into the Atlantic Ocean east of Florida, across Brazil, through the Antarctic Ocean, near the south pole of the earth, northward through Australia, the Indian Ocean. Russia, near the north pole of the earth, and back again. The other is a nmeh smaller closed curve, called the "Siberian Oval." because it is contained in Eastern Siberia and China. See ilAciNETiSM.
