I understood it fine. It took a long time to amass the requisite familiarity with a broad spectrum of thinkers and a lot of manual effort to parse and make sense of how they use specific words and turn of phrase to refer to specific things; and not often in a way that is compatible with others' way of speaking.

In short, philosophy by its nature requires a sort of jargon that is similar to technical (i.e. programming) jargon; without that understanding, you will be getting a limited layer of data; references without referents.
