no. your "reason" is essentially just that some total moron might
threaten to punish you unless you memorize the definitions. you could
as easily use such a "reason" to justify any arbitrarily stupid
behavior.

|The first question in the exam is likely to be something

|
|1. Give the definition of a vector space.
|
|Or perhaps
|
|2. Let X be ....
|Prove that X is a vector space.
|
|(How is this done? By checking all the conditions that appear in the
|definition of "vector space", so again one needs to be able to write
|this down.)
