"Higher" education has a long history. You have thinkers in every culture and every age. You actually have thinkers of both sexes! Some pressures for higher education came from the Roman Catholic church. To understand more and more and to answer pesky questions that arose over time, it was necessary to learn Hebrew, Greek and Latin. Learning those languages led to admiring and copying some of the practices more ancient writers practiced. But you quickly find that going down to Barney's Bar, you may hear uses of language that don't conform to recommendations made by grammarians.
My friend wants me to change "It's her" to "It's she" but that's not the way my people talk. Sorry !
