“I once heard that all reactions to life could be summed up in one of three words every child knows: yikes, yum and yuk. The 100,000 other words in the English language are just refinements and explications of the basic emotions conveyed by these three words. “Yikes” expresses the primary negative but protective emotion of fear; “yum” and “yuk” are the simplest ways to express the fundamental judgments of good and bad which underlie all of life’s experiences.”
