Summa Logicae (c. 1323), Prefatory Letter, as translated by Paul Vincent Spade (1995) http://www.pvspade.com/Logic/docs/ockham.pdf <br class="br">Context: Logic is the most useful tool of all the arts. Without it no science can be fully known. It is not worn out by repeated use, after the manner of material tools, but rather admits of continual growth through the diligent exercise of any other science. For just as a mechanic who lacks a complete knowledge of his tool gains a fuller [knowledge] by using it, so one who is educated in the firm principles of logic, while he painstakingly devotes his labor to the other sciences, acquires at the same time a greater skill at this art.

Canto I, line 81
Hudibras, Part I (1663–1664)
Context: For rhetoric, he could not ope
His mouth, but out there flew a trope;
And when he happen'd to break off
I' th' middle of his speech, or cough,
H' had hard words, ready to show why,
And tell what rules he did it by;
Else, when with greatest art he spoke,
You'd think he talk'd like other folk,
For all a rhetorician's rules
Teach nothing but to name his tools.
