"But to restrict thinking to the patterns merely of English […] is to lose a power of thought which, once lost, can never be regained. It is the 'plainest' English which contains the greatest number of unconscious assumptions about nature. […] We handle even our plain English with much greater effect if we direct it from the vantage point of a multilingual awareness."
