Thomas Edward Kebbel, Dictionary of National Biography… (1886)
“ Many who listened to Canning thought him only a consummate actor, nothing doubting his intellectual belief in the doctrines he was enforcing, but uncertain only whether his feelings were engaged to the extent which his language would imply. It is commonly supposed that rhetoric and passion do not mingle very kindly with each other. Mr. Stapleton, however, has proved beyond risk of contradiction that, if any such rule holds good, Canning at least was an exception to it, and that in all his great orations, however elaborate the texture, he spoke from his heart. ”
