The influence of Al-Farabi upon two of 13th century's most prominent Latin scholastics, Albertus Magnus and his student, St. Thomas Aquinas, is profound. Hammond documents the similarities by placing Al-Farabi's arguments "side by side with those of St. Thomas in order to aid the reader in comparing them."[^44] Thus, "we see without doubt the influence of the former [Al-Farabi] on the latter [St. Thomas] but not vice versa." Further, "Albertus Magnus and St. Thomas and others borrowed from him a great amount of material hitherto regarded by many as a product of their speculation, while in reality it is not."
