The Lathe of Heaven, by U. K. le Guin.
Re-read again, and something really caught my eye this time. Dr. Haber's perspectives are typical scientist attitudes -- in particular, the desire to stand outside of a system and observe/manipulate it fully, which is completely impossible -- and thus his failures and frustrations are those quintessential scientist failures and frustrations. Where do the ends justify the means, if ever? Nothing ever is neat and orderly, dammit! Life never starts over, fresh. If-only, if-only, if-only.
