THE BASIS OF ANALOGY. 



For example, when lirewstcr was advancing the 

 theorv that all the m-'is in .-jiace are the aliodes of lite, 

 lie took the aualoiry in this \vay: II, > pointed out that 

 all the parts of the earth are inhabited, that it seemed 

 (he purpose of tho Creator to supply lifu niust abun- 

 dantly, on land, in sea, in temperate zone. In torrid 

 /one, and in arctic zone, maintaining it at all hi^hts 

 above the sea level, and at all depths below the surface 

 of the earth. Every p:irt of th> earth H"i-ni"d to be 

 Intended to bo the abode of life. That was a true 

 analoiry; but then that shows us only in what way a 

 world is inhabited when it Is passing through tho spe- 

 cial sta^.! of time intended for its habltability. We 

 inn>t not overlook the olher analogy of the past condi- 

 tion of the earth that shuws us so clearly those 

 Ions intervals of time when no life at all ex- 

 isted, and we are bounrt to take this analogy, 

 and to accept, not as a mere fancy, but as a probable 

 theory, tho view that tho various orbs forming the soiar 

 s\ s'eni are only intended to be lor a short time the 

 abode of life. Then we may proceed to inquire whether 

 this or that member of the solar evstem seems to be at 

 the present time, likely to be the abodo of life. It seems 

 to me it is the just way to view the matier. We are to 

 form our idea of tho solar system from the knowledge 

 of our earth, which is a member of it; and so in the 

 case of suns, we must take what we know of our 

 'bright, particular star" rho sun and from that 

 knowledge inter whether iho sun is intended to be for 

 the greater part of its existeuce the center of the plan- 

 etary system, and then what are tho conditions under 

 winch the various planets traveling around other suns 

 may probably exist. We will now have the room dark- 

 ened and a view of the sun placed upon the screen. 



PERIOD WHEN THE SUN'S HEAT SUPPORTS LIFE. 



We have in our sun a scene of continual activity, and 

 wo have there tho same argument th-it is derived Iroin 

 the earth. Activity implies life, implies a certain 

 deflmto period during which life exists. We know the 

 activity of the earth has had a beginning and will have 

 an end. Wo infer that the activity of our sun has had 

 a beginning and will have an end. We recounize in tho 

 pa>t history of the sun that it was then intended to 

 sway the, various members of tho solar system, and to 

 supply them with tho requisite quantities of light and 

 heat. 



It was only when the sun had contracted that the 

 system, properly so called, began to exist. Now wo see 

 all these wonderful processes, how its face becomes 



covered over with spots, and WO know that they indi- 

 cate enormous disturbances, eruptions froai b,-low, with 

 all tho cyclonic disturbances which sweep over the, sun, 

 and then with that glory o( light now depicted before 

 you. Not that we always see it, but we know it is there, 

 that the glorious corona spreads around, and so wo 

 have a picture of what our sun is. 



Bat you are to consider whethef it is possible for tho 

 sun to supply in the tutnre. light and heat for the worlds 

 around It. All tho theories wo have, point clearly to a 

 dellnite period when exhaustion must supervene. 

 Whether we regard the downfall of meteoric matter, or 

 the contraction of the sun. or chemical proi-'.-^es. In ro- 

 ni>ect to .ill MUM processes as arc connected with tho 

 supply of the sun's heat, wo seo that every ono of these 

 process--* must have an end, and tho time will come that 

 the sun will not have that high temperature which ho 

 s. upon the worlds urouud him. liven though wo
