Facile credo, plures esse Naturas invisibles quam visibiles in rerum universitate. Sed horum [sic] omnium familiam quis nobis enarrabit? et gradus et cognationes et discrimina et singulorum munera? Quid agunt? quae loca habitant? Harum rerum notitiam semper ambivit ingenium humanum, nunquam attigit, Juvat, interea, non diffiteor, quandoque in animo, in tabula, majoris et melioris mundi imaginem contemplari: ne mens assuefacta hodiernac vitae minutiis se contrahat nimis, et tota subsidat in pusillas cogitationes. Sed veritati interea invigillandum est, modusque servandus, ut certa ab incertis, diem a nocte, distinguamus.
---T. Burnet
"I can easily believe that there are more invisible than visible beings in the universe. but of their families, degrees, connections, distinctions, and functions, who shall tell us? How do they act? Where are they found? About such matters the human mind has always circled without attaining knowledge. Yet I do not doubt that sometimes it is well for the soul to contemplate as in a picture the image of a larger and better world, lest the mind, habituated to the small concerns of daily life, limit itself too much and sink entirely into trivial thinking. But meanwhile we must be on watch for the truth, avoiding extremes, so that we may distinguish certain from uncertain, day from night."
From Ligeia, by E.A. Poe:
"Out--out are the lights--out all!
And over each quivering form,
The curtain, a funeral pall,
Comes down with the rush of a storm,
And the angels, all pallid and wan,
Uprising, unveiling, affirm
That the play is the tragedy, 'Man'
And its hero the Conqueror Worm."
A note from ME:
Remember that humans are not the most powerful creatures on earth. We do not control all we see. We are not lords of the earth, for it is the tiny, unseen, ephemeral, beings--viruses and such--that drop us to our knees...
