Mind and soul,
I say, are held conjoined one with other,
And form one single nature of themselves;
But chief and regnant through the frame entire
Is still that counsel which we call the mind,
And that cleaves seated in the midmost breast.
Here leap dismay and terror; round these haunts
Be blandishments of joys; and therefore here
The intellect, the mind. The rest of soul,
Throughout the body scattered, but obeys—
Moved by the nod and motion of the mind.
This, for itself, sole through itself, hath thought;
This for itself hath mirth, even when the thing
That moves it, moves nor soul nor body at all.Besides, when these our limbs are given o’er
To gentle sleep and lies the burdened frame
At random void of sense, a something else
Is yet within us, which upon that time
Bestirs itself, receiving wisdom,
All motions of joy and phantom cares of heart.
— Lucretius (99-55 BCE)
