"Though intelligence is powerless to modify character, it is a dab hand at finding euphemisms for its weaknesses"

This quote by Quentin Crisp suggests that knowledge is not able to transform a person's character, but it can be utilized to locate methods to soften the weak points of character. To put it simply, knowledge can be used ahead up with even more polite or less offending ways to explain a person's problems. This is a type of euphemism, which is the use of a milder or less straight word or expression to refer to something undesirable or unpleasant. As an example, instead of saying somebody slouches, one could say they are "much less determined". This quote indicates that knowledge can be made use of to make an individual's weaknesses much more tasty, yet it can not in fact transform the underlying personality.
