He knew the risks associated with this obsessive, neurotic behavior, and the results were as bad as predicted. The first two volumes of Affect Imagery Consciousness (AIC) were released in 1962 and 1963, Volume III in 1991 shortly before he succumbed to a particularly virulent strain of small cell lymphoma, and Volume IV a year after his death.
