Anselm of Canterbury in Latin — Read the Proslogion
Anselm of Canterbury (1033–1109) is the father of scholastic theology and the author of the famous ontological argument for the existence of God. In his Proslogion he seeks “faith seeking understanding” (fides quaerens intellectum) — and his medieval Latin is a classic of philosophical reading. That is where our idea comes in: read the same author in stages, from a gentler passage to the unchanged original. This page belongs to our Learn Latin section and leads into our in-app reader.
Important: this is not a grab-bag of level sentences — you practise those in the Sentence Quiz. In the reader you get the real author as a connected text. Because context carries understanding — fragments never become reading.

Who was Anselm of Canterbury?
Anselm of Canterbury (1033–1109), a Benedictine monk and later Archbishop of Canterbury, was the leading theologian of the early scholastic age. In his Proslogion he set out the ontological argument: God is “that than which nothing greater can be thought.” His method — credo ut intelligam, “I believe in order to understand” — shaped Western philosophy down to Descartes and Kant.
Anselm’s definition of God — in the original
The heart of the ontological argument is a single definition of God, from Proslogion 2:
Credimus te esse aliquid, quo nihil maius cogitari possit.
Anselm von Canterbury, Proslogion 2
Our translation: “We believe you to be something than which nothing greater can be thought.” From this one sentence Anselm argues that God must exist not only in the mind but in reality — for a God who exists in reality is greater than one thought of as existing only in the mind.
You can check the Latin and the argument against free, scholarly sources: the Stanford Encyclopedia of Philosophy (Anselm), the original text of the Proslogion on Wikisource, and the overview at Wikipedia.
In stages to the original — how the app grades the text
Reading research names a hard threshold: only when you know about 95% of the words in a paragraph do you read fluently. Jump straight into Anselm’s scholastic chains and those 95% are almost always missing. So we read the same Anselm material in stages, up to the unchanged original.
In our in-app reader the Proslogion is built this way — the same argument across stages:
| Stage | Collection in the app | Focus |
|---|---|---|
| stage L21 | Proslogion 2–3 | The definition of God |
| stage L27 | Proslogion 4–5 | The proof carried through |
The same argument, two stages — the Proslogion
On the left the gentler entry from “Proslogion 2–3 (stage L21)”, on the right Anselm’s harder original from “Proslogion 4–5 (stage L27)”:
Entry · stage L21 (Proslogion 2)
“Et quidem credimus te esse aliquid, quo nihil maius cogitari possit.”
And indeed we believe you to be something than which nothing greater can be thought.
Original · stage L27 (Proslogion 4)
“Existit ergo procul dubio aliquid, quo maius cogitari non potest, et in intellectu et in re.”
There exists, therefore, beyond doubt something than which nothing greater can be thought, both in the mind and in reality.
The same idea — only the difficulty grows: the plain profession of belief against the full proof, with the ablative of comparison (quo maius) and the contrast in intellectu / in re (in the mind / in reality).
Key idea: the hardest text does not make you better — the one you understand at 95% does, and then one step higher.

The Anselm pitfalls — and how to crack them
Anselm writes clear but tightly-argued scholastic Latin. Three features cost the most marks:
1. The ablative of comparison (quo maius)
Students stumble over aliquid, quo maius nihil cogitari potest and read the relative quo as a locative (“in which”). It is an ablative of comparison: “something than which nothing greater can be thought.”
2. res = reality, not “thing”
Anselm sharply distinguishes existence in intellectu (in the mind) from in re (in reality). Here res must never be rendered “thing” but “reality”.
3. Scholastic argument loops
Anselm repeats the same phrase (quo maius cogitari non potest) in ever new conditional structures. Hold the thread: mark what is being supposed and what follows.
| Pitfall | Signal | Most common mistake |
|---|---|---|
| Ablative of comparison | quo maius + comparative | read as locative “in which” |
| res | in re vs in intellectu | translated “thing” instead of “reality” |
| Scholastic loops | the same phrase repeated | losing the thread of the argument |
Frequently asked — Anselm of Canterbury
What is Anselm’s ontological argument?
In the Proslogion Anselm defines God as ‘that than which nothing greater can be thought’ and argues that such a being must exist in reality, not only in the mind — for real existence is greater than mere thought.
What does ‘fides quaerens intellectum’ mean?
‘Faith seeking understanding’ — the original subtitle of the Proslogion. It expresses Anselm’s method: he believes first, then uses reason to understand what he believes (‘credo ut intelligam’).
Is Anselm hard to translate?
His Latin is clear but tightly argued. The main difficulties are the ablative of comparison (quo maius), the philosophical use of res (‘reality’), and the repetitive scholastic structures. Read in stages and it becomes manageable.
When did Anselm live?
1033 to 1109. He was a Benedictine monk, abbot of Bec and then Archbishop of Canterbury, and is counted among the founders of scholasticism.
