What are grounds?
Toulmin thought that grounds were necessary in order for an argument to be convincing. Grounds are the supporting evidence that cause an audience to accept your reason. Grounds are facts, data, statistics, casual links, testimony, examples, anecdotes. Toulmin suggests that grounds are "what you have to go on" in an argument - the stuff you can "point out and present before a jury." (Ramage, Bean, and Johnson, 76)
