of　it　by　man　is　inconsistent　with　the　first　principles　of　ethics；　what
becomes　of　this　surprising　theory？

Let　us　understand；　once　for　all；　that　the　ethical　progress　of　society
depends；　not　on　imitating　the　cosmic　process；　still　less　in　running
away　from　it；　but　in　combating　it。　It　may　seem　an　audacious　proposal
thus　to　pit　the　microcosm　against　the　macrocosm　and　to　set　man　to
subdue　nature　to　his　higher　ends；　but　I　venture　to　think　that　the
great　intellectual　difference　between　the　ancient　times　with　which　we
have　been　occupied　and　our　day；　lies　in　the　solid　foundation　we　have
acquired　for　the　hope　that　such　an　enterprise　may　meet　with　a　certain
measure　of　success。

The　history　of　civilization　details　the　steps　by　which　men　have
succeeded　in　building　up　an　artificial　world　within　the　cosmos。
Fragile　reed　as　he　may　be；　man；　as　Pascal　says；　is　a　thinking　reed：
＇Note　22＇　there　lies　within　him　a　fund　of　energy　operating
intelligently　and　so　far　akin　to　that　which　pervades　the　universe；
that　it　is　competent　＇84＇　to　influence　and　modify　the　cosmic　process。
In　virtue　of　his　intelligence；　the　dwarf　bends　the　Titan　to　his　will。
In　every　family；　in　every　polity　that　has　been　established；　the　cosmic
process　in　man　has　been　restrained　and　otherwise　modified　by　law　and
custom；　in　surrounding　nature；　it　has　been　similarly　influenced　by　the
art　of　the　shepherd；　the　agriculturist；　the　artisan。　As　civilization
has　advanced；　so　has　the　extent　of　this　interference　increased；　until
the　organized　and　highly　developed　sciences　and　arts　of　the　present
day　have　endowed　man　with　a　command　over　the　course　of　non…human
nature　greater　than　that　once　attributed　to　the　magicians。　The　most
impressive；　I　might　say　startling；　of　these　changes　have　been　brought
about　in　the　course　of　the　last　two　centuries；　while　a　right
comprehension　of　the　process　of　life　and　of　the　means　of　influencing
its　manifestations　is　only　just　dawning　upon　us。　　We　do　not　yet　see
our　way　beyond　generalities；　and　we　are　befogged　by　the　obtrusion　of
false　analogies　and　crude　anticipations。　But　Astronomy；　Physics；
Chemistry；　have　all　had　to　pass　through　similar　phases；　before　they
reached　the　stage　at　which　their　influence　became　an　important　factor
in　human　affairs。　Physiology；　Psychology；　Ethics；　Political　Science；
must　submit　to　the　same　ordeal。　Yet　it　seems　to　me　irrational　to　doubt
that；　at　no　distant　period；　they　will　work　as　great　a　revolution　in
the　sphere　of　practice。

＇85＇　The　theory　of　evolution　encourages　no　millennial　anticipations。
If；　for　millions　of　years；　our　globe　has　taken　the　upward　road；　yet；
some　time；　the　summit　will　be　reached　and　the　downward　route　will　be
commenced。　The　most　daring　imagination　will　hardly　venture　upon　the
suggestion　that　the　power　and　the　intelligence　of　man　can　ever　arrest
the　procession　of　the　great　year。

Moreover；　the　cosmic　nature　born　with　us　and；　to　a　large　extent；
necessary　for　our　maintenance；　is　the　outcome　of　millions　of　years　of
severe　training；　and　it　would　be　folly　to　imagine　that　a　few　centuries
will　suffice　to　subdue　its　masterfulness　to　purely　ethical　ends。
Ethical　nature　may　count　upon　having　to　reckon　with　a　tenacious　and
powerful　enemy　as　long　as　the　world　lasts。　But；　on　the　other　hand；　I
see　no　limit　to　the　extent　to　which　intelligence　and　will；　guided　by
sound　principles　of　investigation；　and　organized　in　common　effort；　may
modify　the　conditions　of　existence；　for　a　period　longer　than　that　now
covered　by　history。　And　much　may　be　done　to　change　the　nature　of　man
himself。　＇Note　23＇　The　intelligence　which　has　converted　the　brother　of
the　wolf　into　the　faithful　guardian　of　the　flock　ought　to　be　able　to
do　something　towards　curbing　the　instincts　of　savagery　in　civilized
men。

But　if　we　may　permit　ourselves　at　larger　hope　of　abatement　of　the
essential　evil　of　the　world　than　was　possible　to　those　who；　in　the
infancy　of　＇86＇　exact　knowledge；　faced　the　problem　of　existence　more
than　a　score　of　centuries　ago；　I　deem　it　an　essential　condition　of　the
realization　of　that　hope　that　we　should　cast　aside　the　notion　that　the
escape　from　pain　and　sorrow　is　the　proper　object　of　life。

We　have　long　since　emerged　from　the　heroic　childhood　of　our　race；　when
good　and　evil　could　be　met　with　the　same　〃frolic　welcome；〃　the
attempts　to　escape　from　evil；　whether　Indian　or　Greek；　have　ended　in
flight　from　the　battle…field；　it　remains　to　us　to　throw　aside　the
youthful　overconfidence　and　the　no　less　youthful　discouragement　of
nonage。　We　are　grown　men；　and　must　play　the　man

　　　　　〃。。。strong　in　will
　　　　　To　strive；　to　seek；　to　find；　and　not　to　yield；〃

cherishing　the　good　that　falls　in　our　way；　and　bearing　the　evil；　in
and　around　us；　with　stout　hearts　set　on　diminishing　it。　So　far；　we　all
may　strive　in　one　faith　towards　one　hope：

Note　1　（p。　49）。

I　have　been　careful　to　speak　of　the　〃appearance〃　of　cyclical　evolution
presented　by　living　things；　for；　on　critical　examination；　it　will　be
found　that　the　course　of　vegetable　and　of　animal　life　is　not　exactly
represented　by；　the　figure　of　a　cycle　which　returns　into　itself。　What
actually　happens；　in　all　but　the　lowest　organisms；　is　that　one　part　of
the　growing　germ　（A）　gives　rise　to　tissues　and　organs；　while　another
part　（B）　remains　in　its　primitive　condition；　or　is　but　slightly
modified。　The　moiety　A　becomes　the　body　of　the　adult　and；　sooner　or
later；　perishes；　while　portions　of　the　moiety　B　are　detached　and；　as
offspring；　continue　the　life　of　the　species。　　Thus；　if　we　trace　back
an　organism　along　the　direct　line　of　descent　from　its　remotest
ancestor；　B；　as　a　whole；　has　never　suffered　death；　portions　of　it；
only；　have　been　cast　off　and　died　in　each　individual　offspring。

Everybody　is　familiar　with　the　way　in　which　the　〃suckers〃　of　a
strawberry　plant　behave。　A　thin　cylinder　of　living　tissue　keeps　on
growing　at　its　free　end；　until　it　attains　a　considerable　length。　At
＇88＇　successive　intervals；　it　develops　buds　which　grow　into　strawberry
plants；　and　these　become　independent　by　the　death　of　the　parts　of　the
sucker　which　connect　them。　The　rest　of　the　sucker；　however；　may　go　on
living　and　growing　indefinitely；　and；　circumstances　remaining
favourable；　there　is　no　obvious　reason　why　it　should　ever　die。　The
living　substance　B；　in　a　manner；　answers　to　the　sucker。　If　we　could
restore　the　continuity　which　was　once　possessed　by　the　portions　of　B；
contained　in　all　the　individuals　of　a　direct　line　of　descent；　they
would　form　a　sucker；　or　stolon；　on　which　these　individuals　would　be
strung；　and　which　would　never　have　wholly　died。

A　species　remains　unchanged　so　long　as　the　potentiality　of　development
resident　in　B　remains　unaltered；　so　long；　e。g。；　as　the　buds　of　the
strawberry　sucker　tend　to　become　typical　strawberry　plants。　In　the　case
of　the　progressive　evolution　of　a　species；　the　developmental
potentiality　of　B　becomes　of　a　higher　and　higher　order。　In
retrogressive　e
