About Al-Ghazali

Abū Ḥāmid al-Ghazālī (1058–1111) taught law and theology in Baghdad before a crisis of certainty drove him from public office into Sufi practice and writing. He mastered the falāsifa well enough to attack their metaphysics in The Incoherence of the Philosophers, then narrated his own epistemic itinerary in Deliverance from Error.

How to read this passage

Epistemology asks whether knowledge is justified true belief, reliable tracking of the world, or something else; it also asks how perception, testimony, memory, and reason contribute. This passage enters that discussion through knowledge, cultivation, practice.

Concepts in this quote

Knowledge
Knowledge is the philosophical study of what we can justifiably claim to know—and where certainty ends.
Cultivation
Cultivation appears in this archive as a live philosophical concern—not a slogan. These verified English passages show how thinkers treat cultivation as a problem of judgment, practice, or explanation.
Practice
Practice is where thought becomes habit: philosophy as a way of living, training, and repeated action.
