Monologium, on the Being of God47 Chapter XLVII. The Son is the intelligence of intelligence and the Truth of truth.

Chapter XLVII. The Son is the intelligence of intelligence and the Truth of truth.

But if the very substance of the Father is intelligence, and knowledge, and wisdom, and truth, it is consequently inferred that as the Son is the intelligence, and knowledge, and wisdom, and truth, of the paternal substance, so he is the intelligence of intelligence, the knowledge of knowledge, the wisdom of wisdom, and the truth of truth.

At si ipsa substantia Patris est intelligentia, et scientia, et sapientia, et veritas, consequenter colligitur quia sicut Filius est intelligentia, et scientia, et sapientia, et veritas paternae substantiae; ita est intelligentia intelligentiae, scientia scientiae, sapientia sapientiae, et veritas veritatis.
