> The standard Shakespeare, the one from Stratford-upon-Avon, allowed his children to grow up illiterate (this is an agreed fact among Shakespeare scholars). For someone who valued the English language so much, who was one of the greatest writers of the English language, it seems unimaginable that he would not have made any effort to see that his children learn to read and write.

His children were all female, no? You didn't educate women in those days.

You are applying 21st century first world standards to 16th century denizens.
