True

Explanation:

Thomas Sheridan and George Campbell are both considered as eminent individuals in the field of public speaking, being great admirers of the nuances associated with the art of speech and furthering their individual philosophies and schools of thoughts. The art of public speaking as grown tremendously since the time of the Greeks, becoming an important method of communication. It can be accepted that any leader worth their salt would be adept at the art of giving speeches. As such, several approaches have been invented, honed, propagated and re-defined over the course of history. This is where Thomas Sheridan and George Campbell come in.

Thomas Sheridan was a major proponent and guiding force of the Elocutionary Movement. This movement, featured in the 18th century, was gathered around the concept of developing a structured approach towards teaching how to master oral speech at a mass level. The movement advocated several principles that could be adopted to learn how to communicate better and deliver better speeches. These principles included the importance of non-verbal gestures, body language, and of course, the presenter's facial expression.

George Campbell was the advocate of epistemological movement. This movement had routes in the idea of rationalism and the scientific approach towards thinking. Epistemology itself is defined as the study of human knowledge. The movement sought to understand the facets of human psychology and implement the learning in the science of rhetoric. It focused on how humans use sensory cues and a rational thought process to make decisions.

Therefore, given what we know about both these individuals, Thomas Sheridan would argue on the concept of rationality while Sheridan would focus more the "art" of oral delivery.
