Shah Waliullah Dehlawi is remembered in physiology for work that changed what the next generation was able to take for granted.
Shah Waliullah Dehlawi was born at Delhi in 1703. His recorded nationality is India. He was educated at Madrasah-i Rahimiyah.
The eighteenth century turned natural philosophy into organised enquiry: expeditions, collections, academies and the beginnings of specialist training.
His research centred on usul al-fiqh, fiqh and science of hadith.
Among his principal works are al-Inṣāf fī bayān asbāb al-Ikhtilāf and book. Physiology advanced through experiments whose ethics each generation has had to re-argue.
The India setting is not incidental. National academies, funding and language decided which findings travelled and which stayed local, in this period as in ours.
The measure that matters is durability. Results that survive re-examination become the floor of a discipline, and it is on that floor that everything afterwards is built.
A number of his statements have been preserved; they appear below.
Death came in 1762, at 59. By then the contribution had passed into the settled body of physiology, where it is used without being credited - the surest sign that it was right.
