I've been studying the book Elementary Lessons in Logic by W. Stanley Jevons. Singular terms are described as such, "Singular term is one which can denote only a single object, so long at least as it is used in exactly the same meaning." General terms are described as such, "General terms, on the contrary, are applicable in the same sense equally to anyone of an indefinite number of objects which resemble each other in certain qualities."
So, is the name of an ideology, like progressivism, a singular or general term? To me, it feels like it could be both, but I think I'm wrong. Progressivism could be a singular term because it always denote the same thing -- a set of ideas to achieve "progress." But at the same time, it seems like a general term because progressivism is the umbrella of various ideas, that, taken all together, form progressivism. Or in other words, without all those ideas, there wouldn't be progressivism.
Anyone can help me out? What are your thoughts?
