The Medieval Church · 1458
On the Beryl
De Beryllo
Nicholas of Cusa · 1401–1464
What it is
A short work using the image of a lens through which the invisible becomes visible, on how the mind may glimpse the coincidence of opposites in God.
Why it lasted
The clearest statement of Cusa's method, and a favourite of later thinkers from Bruno to the German idealists.
