In the realm of the unknown, difficulties must be viewed as a hidden treasure! Usually, the more difficult, the better. It's not as valuable if your difficulties stem from your own inner struggle. But when difficulties arise out of increasing objective resistance, that's marvelous!
To the average mathematician who merely wants to know his work is securely based, the most appealing choice is to avoid difficulties by means of Hilbert's program. Here one regards mathematics as a formal game and one is only concerned with the question of consistency... The Realist position is probably the one which most mathematicians would prefer to take. It is not until he becomes aware of some of the difficulties in set theory that he would even begin to question it. If these difficulties particularly upset him, he will rush to the shelter of Formalism, while his normal position will be somewhere between the two, trying to enjoy the best of two worlds.
Understanding people's difficulties and-just as crucial-helping people understand their own difficulties and teaching them concrete ways to help themselves will help them better deal with their own lives and, in turn, ours.
