We shall introduce the concept of almost causality condition. By defining the almost causality condition we would like to examine the relationship between Woodhouse's causality principle and other known caus\-al\-ity conditions. We show that a series of causality conditions can be characterized by using the almost causality condition.
Keywords: Seifert future set, almost causal, stable causal, Woodhouse causal
