Question 2 [4 points; 300 words]
Consider the following sentence:
(g) Everyone knew that stress caused ulcers, before two Australian doctors in the early 80s proved that ulcers are not caused by stress, but by a bacterial infection.
Describe why this sentence can be considered a problem for the analysis of the verb to know (which you discussed in the previous question).
Your answer should contain the terms presupposition, and contradiction.
Next, try to find a solution for this problem by re-analyzing the presuppositions triggered by know, that explains why sentence (g) is acceptable, but doesn’t dismiss our understanding of sentences (a)-(c).
Discuss pros and cons of your solution [Multiple answers to this last point are possible and it’s a hard question; I want to see a good argument!]
