Ibn al-Haytham Quotes on Truth
Ibn al-Haytham (Alhacen, c.965–c.1040) — the Iraqi-born polymath whose seven-volume Book of Optics (Kitāb al-Manāẓir) reorganized classical optics on a rigorously experimental and mathematical foundation — gave classical Islamic philosophy of science its most influential statement of methodological empiricism. The central commitments — that the truth of natural-philosophical claims must be established through the systematic combination of mathematical demonstration and controlled experimental verification, that the inherited authorities (Aristotle, Galen, Ptolemy) must be tested against direct investigation rather than accepted on the strength of their reputations, and that the seeker after truth must approach the prior tradition with the prepared willingness to revise it — articulate a methodology that the Latin reception (through Witelo and Roger Bacon) and the modern history of science have alike treated as anticipating the seventeenth-century scientific revolution. The framework shaped the Latin Perspectivist optical tradition and the broader medieval and early modern engagement with the philosophical conditions of empirical truth.

“Whosoever seeks the truth will not proceed by studying the writings of his predecessors and by simply accepting his own good opinion of them. Whosoever studies works of science must, if he wants to find the truth, transform himself into a critic of everything he reads . He must examine tests and explanations with the greatest precision and question them from all angles and aspects.”
