HOWEVER, in this _Constitution_, (whatever _natural Causes_ may be advanc’d) the great GOD is indisputably and undeniably the prime and principal _Efficient_: for all other _Causes_, whether proximous or remote, without his _Concurrence_, would be but vain and insufficient, for the following Reasons. I. HE is the only primary AGENT, not _physical_, because not acting _physically_; not operating by _Motion_, because _immoveable_: but without _Motion_, and all other _physical Helps_, he powerfully and clearly displays HIMSELF, most eminently officiating by his own _All-sufficiency_, and Appointment of _Nature_. II. HE likewise, as the prime, common, remote, and physical CAUSE, governs and directs all _other secundary Causes_ supereminently, which are subjected to, and dependent upon HIMSELF; in constituting, organizing, and fomenting the _CONCEPTION_. III. HE finally, as the proper, proximous, and immediate CAUSE, or AGENT, directing _none else_, nor using any _other Assistance_ in the Work, neither being _directed_ nor _assisted_ by any _other_, gives to the organiz’d human FOETUS its greatest Completion; and the _ultimate finishing Stroke_ of consummate _Perfection_, by infusing and communicating to it a _Mind_ in a rational _SOUL_, by which the FOETUS becomes _MAN_. AND this _Infusion_ comes immediately from, and of HIMSELF, who is (in _Aristotle_’s Words): “The _Form_ and _Former_ of the UNIVERSE, the ultimate _End_, the final and efficient _Cause_ of all _celestial Bodies_, and _created Beings_.” BUT now, as to the _Time_ of this great Work of ANIMATION, _Naturalists_ agree, that it requires double the _Space_ that FORMATION had from _Conception_: which seems so far probable, because at _that time_, and no sooner, the _Infant_ may be sensibly perceiv’d to move; and _that_ by the _Influence_ of calid and siccid MARS, who (according to _Astrologers_) now takes charge of it in the _third Month_. For by virtue of his _hot Quality_, he perfecteth the _three_ principal Members, separating the _Legs_, _Arms_, and _Head_ (in due proportion) from the _rest_: Wherefore this _auspicious Planet_ is called the AUTHOR of the _Infant’s Motion_. So that, in fine, conformable to what is laid down in the preceeding _Chapter_, the Work of ANIMATION is perfected, at soonest, about the 70th, and at latest, about the 100th Day from _CONCEPTION_. Which being done, I proceed to the next _principal Work_ in constituting the MAN. [Illustration] CHAP. IX _Of the MATURATION of the INFANT._ NATURALISTS allow the _Infant_, for its ripening in the _Womb_, and to the legitimate _Time of Birth_, treble the _Space_ that ANIMATION had; as _Physicians_ agree in allowing _this_ treble the Time that the _first Motion_ had from _Conception_: and from hence the 4th, 5th, 6th, 7th, _&c._ are called _ripening Months_.
