In a 4 January column for the Daily Wire, Dennis Prager, talk show host and founder of the partisan YouTube channel Prager U, opines that it is often very difficult to know what the left stands for or wants. Prager stresses that there is no standard book that might provide insight into the question:
It is not easy to understand what the Left—as opposed to liberals—stands for. If you ask a Christian what to read to learn the basics of Christianity, you will be told the Bible. If you ask a (religious) Jew, you will be told the Hebrew Bible and the Talmud. If you ask a Mormon, you will be told the Bible and the Book of Mormon. Ask a Muslim, and you will be told the Quran. But if you ask a leftist what one or two books you should read to understand leftism, every leftist will give you a different answer. Although leftism is complex, here is a brief overview of the books you'll need to get a basic understanding.
