It is in fashion to sling mud at Dr. Atta-ur-Rehman, but I regard him to be a great man. He encouraged HEC to send thousands of youths abroad on scholarships for PhD after which they have to work for 5 years in Pakistani universities. They will in turn nurture another, much bigger group of PhDs. This chain reaction of doctors of various disciplines would thus go on, bringing a great harvest of qualified people for us. It is the most laudable effort for an everlasting educational revolution in Pakistan. -ZAFAR ULLAH, Sargodha, via e-mail, July 13.
