"For example, in an industrial culture such as ours there is a correlation between the amount of time a task takes and the amount of labor it takes to accomplish the task. This correlation is part of what allows us to view time and labor metaphorically as resources and hence to see a similarity between them. It is important to remember that correlations are not similarities. Metaphors that are based on correlations in our experience define concepts in terms of which we perceive similarities." (#60 2624)
