- In your terminology then, a confession on your part in the form
- "surely I broke the vase" must not be taken to mean that you did break
- the vase, although an indignant denial in the form "surely I did not
- break the vase" or "I did not surely break the vase" implies that you
- did not break the vase. If you say "surely, if I broke the vase I must
- have smashed the window" and later admit that you broke the vase, we
- must be careful not to claim that you stand convicted on your own
- evidence of having smashed the window, but only of having surely
- smashed the window. I think this whole thing is a very shrewd move on
- your part in that it practically guarantees that whatever misdemeanors
- you may commit in the future, you will be able to confuse your
- interrogators to the point where they prefer to drop all charges.
- Presuming, of course, that your lawyer can convince the court that
- this person, being an Intuitionist, must be interrogated in his own
- language.
