Now--after a series of books on self-understanding and male-female relationships--Viscott tells us that, after falling in love with a new woman, he has learned he didn't know what he was talking about. ""My prior understanding of love,"" he says, ""was that of a person thinking in a second language, just a bit removed from the truth."" Unfazed, he serves up much the same advice as in How to Live with Another Person: ""Real growth is only possible if you accept the ever evolving reality that you share together,"" and, ""No matter what sort of character types you or your partner happen to be, it is still possible to have a loving, lasting relationship."" As in his treatise on self-analysis, The Viscott Method, he keeps the reader busy with innumerable lists and/or ""shared"" diaries plus occasional tape recordings on such matters as fears that prevent commitment, what turns you on sexually, disagreements, jealousy, and so on. Despite this patent triteness, his publishers are definitely upbeat: the book's appearance coincides with the debut of Viscott's very own nationally syndicated TV show.
