Is perfect participle, in spite of the general notion, used both as perfect passive participle and perfect active participle?
Spinoza, Ethics, De Dei, Propositio 15, Scholium:
nam omnes qui naturam divinam aliquo modo contemplati sunt, negant Deum esse corporeum
White translates it:
for all men who have in any way looked into the divine nature deny that God is corporeal
