Note 117 — XIII. LOCKE. (1632-1704).
Reading edition
Pope seems to contrast Montaigne and Locke:
“But ask not to what doctors I apply! “Sworn to no master, of no sect am I: “As drives the storm, at any door I knock, “And house with Montaigne now, or now with Locke.” Satires iij., 26.
Perhaps as Dr. Abbott suggests he took Montaigne as representing active and Locke contemplative life.
