This is the right-leaning Lost Arrow-size crack rising out of the bottom of the dark gully/wide chimney left of Look Who's Talking. If you like placing tiny gear in spicy situations, Empty Rhetoric is the route for you. It actually climbs well (the Ruckmans gave it one out of three stars in their 1998 guide) and with patience and the right gear, you can sew it up. But because the route leans to the right as does the ground, and there is a wall a body length behind you, as well as a ledge that could flip you over half-way, the R rating is probably warranted.
Battle up the LA crack to a horizontal break (avoid the urge to clip the fourth bolt of Hyperbole), move right to catch another, slightly thinner crack, and continue battling to its top. Do not be dismayed by the occasional patch of lichen or nice garden feature at the break; they are inconsequential. Empty Rhetoric ends at a large sloping ledge with chain anchors. If more climbing is desired, consider continuing up on DNR (the arete just left), Hyperbole (the bolts just right), or Look Who's Talking (the vegetated crack system to the far right).
Empty Rhetoric can be accessed by downclimbing the wide chimney/gully left of Look Who's Talking. However, a far superior way to reach the base of Empty Rhetoric is to follow the description for Direct North Ridge and Hyperbole. Empty Rhetoric is the obvious slanting seam about 10 feet right of Hyperbole's bolts.
The smallest brass/steel (offsets useful) and up, the smallest cams to maybe one-inch, and a gold Camalot or its equivalent for a pod near the top. Might want a helmet.
