It is here where I present my original concept of cultureCulture as a set of propositional attitudesAttitudes to condition purposeful actions. CultureCulture is thus attributed to individuals rather than communities. A human being is then a system that not only reacts to but also initiates changesChange in an ordered way. This is how cultureCulture fluctuates. Cultural difference is then discussed. I claim it is this difference with respect to which cultural fluctuation is possible but not necessary, and where the changeChange is caused by human actions. Such actions provoke counterparts to alter their previous behavior. In this respect culturesCulture may, but need not, be calibrated despite being changed. Since a crackCrack is an irreversible eventEvent, it is confronted with a borderBorder, the crossing of which opens new perspectives.
