Equivocation is when a word is used in two different senses in an argument. Take for example the following syllogism:
A hamburger is better than nothing
Nothing is better than good health
Therefore a hamburger is better than good health
The word 'nothing' has two meanings. In the first line it means the absence of something. In the second line it refers to a range of things, as in: 'of all the good things in life, nothing is better than good health.' This accounts for why the conclusion sounds so strange. This linguistic device can be used to manipulate people, by making false arguments sound convincing.
Can you describe the use of equivocation in the cartoon?
