About Galen

 
 

This laboratory is name after Galen (ca. 129-206 C.E.), a Greek physician. He represents a capstone on a tradition of medicine established by Hippocrates that was eventually passed on to Renassiance scholars. He is known for his meticulous observation and empirical work. In other words, his scientific approach to medicine. For these reasons, this group has been named the Galen Lab. We seek to use a scientific, empirically-based approach to software engineering, in building and validating software tools and methods, and our concern with research methdology.

Incidentally, Galen is the name of the the digital library at University of California, San Diego, a think tank on health and tax policy, and medical informatics software funded by the EU.

Background

Here is a story about Galen that is cited in an introductory text on research methdology (Ray, 1993, p. 11) that is used to illustrate his scientific approach.

"In the second century A.D., Galen, a well-known physician, described a woman who complained of insomnia (Mesulam and Perry, 1972). The problem was to determine the factors that led to the insomnia. Galen first decided that the problem was not mainly physical. Following this determination, he began to notice the woman's condition during his examinations. It happened that during one examination, a person returning from the theater mentioned the name of a certain dander, Pylades. At this point Galen observed that the woman's pulse increased along with a change in her facial color and expression. What did Galen do next? To answer his questions as to what was affecting the women, he began to experiment. In his own words:
"The next day, I told one of my following that when I went to visit the woman he was to arrive a little later and mention than Morphus was dancing that day. When this was done the patient's pulse in no way changed. And likewise, on the following day, while I was attending her, the name of the third dancer was mentioned, and in like fashion the pulse was hardly affected at all. I investigated the matter for a fourth time in the evening. Studying the pulse and seeing that it was excited and irregular when mention was made that Pylades was dancing, I concluded that the lady was in love with Pylades, and in the days following, this conclusion was confirmed exactly. (Galen, 1827, trans)
"Galen went pas observation and began to ask, "I wonder what will happen if I do this?" He performed what would now call a single-subject experiment. Notice that Galen checked to determine that it was not the name of just any dancer that produced a change in pulse rate or even just a man's name. He sought to discover what factors brought on an irregular pulse by examining a number of alternatives. From this investigation, he concluded that only the name of one particular man, repeated on different occasions, produced the effect."
