I think that the current scientific thought is twofold - (1) You would eventually come up with your own words to describe what you see (2) A good deal of the part of the cortex which deals with language is developed by hearing it said. I dont know if coming up with your own words and talking to yourself counts. I DO know that in Romania, after the fall of communism, whole orphanages of infants were almost abandoned. The infants were just given enough food and diaper changing to live, but they werent held or touched much at all. As a result, these babies never developed the ability to empathize with other human beings, and they are largely a criminal element of the teenage population at this time, having alot of the characteristics of psychopaths. Unfortunately, as we have found out too late, the sense of touch, and being touched by another when we are young, produces certain hormones which allow bonding. Very sad, very scary.
