I have found that for a number of students doing proofs is an unnecessary evil. For some of them it is like a painful visit to the local dentist. I thought I had explained the need for proves but it still puts a number of students off. What motivating reasons can I give students for them to at least understand the logical deduction of proofs and why they need them? I have informed them of things like absolute truth, permanent, make sure our statements are correct, more powerful than a scientific proof etc.
