You might want to look up what a Ph.D. is, and what the word philosophy means.
While the word “philosophy” can mean the study of existentialist nonsense, and it is possible to get a Ph.D. in that field, the word has other meanings. Literally, it means “love of knowledge”, from “philo”=”loving” and “sophia”=”knowledge” or “wisdom”.
A Ph.D. is a degree awarded for demonstrating an ability to conduct high-quality research in a field. It is most certainly an appropriate degree to award to scientists.
Yeah, right......
