From a notebook I kept in 1991, I find *Capella’s Sevel Liberal Arts* inscribed on the first page:

The Facts You Need to Know

• Music Theory: for singing hymns
• Geometry: for measuring things
• Arithmetic: for adding things
• Astronomy: for knowing what day it is

How to Use the Things You Know

• Grammar: for getting it right
• Rhetoric: for putting it in letters
• Logic: to explain things clearly
