To withdraw myself from myself has ever been my sole, my entire, my sincere motive in scribbling at all.

The insatiate itch of scribbling.

For there's nothing we read of in torture's inventions, Like a well-meaning dunce, with the best of intentions.

A good intention clothes itself with sudden power.

What makes like dreary is the want of motive.

Iago's soliloquy--the motive-hunting of a motiveless malignity--how awful it is!
