nce all judgment is the act of him who
judgeth, it is necessary that every one should perfect his operation by
his own power and not by the force of any other.

Quondam porticus attulit
Obscuros nimium senes
Qui sensus et imagines
E corporibus extimis
Credant mentibus imprimi, 5
Vt quondam celeri stilo
Mos est aequore paginae,
Quae nullas habeat notas,
Pressas figere litteras.
Sed mens si propriis uigens 10
Nihil motibus explicat,
Sed tantum patiens iacet
Notis subdita corporum
Cassasque in speculi uicem
Rerum reddit imagines, 15
Vnde haec sic animis uiget
Cernens omnia notio?
Quae uis singula perspicit
Aut quae cognita diuidit?
Quae diuisa recolligit 20
Alternumque legens iter
Nunc summis caput inserit,
Nunc decedit in infima,
Tum sese referens sibi
Veris falsa redarguit? 25
Haec est efficiens magis
Longe causa potentior
Quam quae materiae modo
Impressas patitur notas.
Praecedit tamen excitans 30
Ac uires animi mouens
Viuo in corpore passio.
Cum uel lux oculos ferit
Vel uox auribus instrepit,
Tum mentis uigor excitus 35
Quas intus species tenet
Ad motus similes uocans
Notis applicat exteris
Introrsumque reconditis
Formis miscet imagines. 40

Cloudy old prophets of the Porch[175] once taught
That sense and shape presented to the thought
From outward objects their impression take,
As when upon a paper smooth and plain
On which as yet no marks of ink have lain
We with a nimble pen do letters make.
But if our minds to nothing can apply
Their proper motions, but do patient lie
Subject to forms which do from bodies flow,
As a glass renders empty[176] shapes of things,
Who then can show from whence that motion springs
By force of which the mind all things doth know?
Or by what skill are several things espied?
And being known what power doth them divide,
And thus divided doth again unite,
And with a various journey oft aspires
To highest things, and oft again retires
To basest, nothing being out of sight,
And wh
