Context

The 'organizing principal' that I have chosen is context. An example of context from the reading is the anecdote about the origin of X-rays. German physicist Wilheim Roentgen made this discovery when he was looking at a fogged photographic plate while he was working with some vacuum tubes. When he took an X-ray of his wife, he was able to see her bones and her wedding ring. By using context and taking the clues from the fogged plate that he had found earlier, Roentgen managed to create the X-ray and discover a way to help people with their broken bones.
An example that I have made of this principle is that I went online and looked up a sentence that contained a word that I did not know. I went on a web sight and found a sentence. The word was insouciance, and the sentence was: "His insouciance will come back to bite him, if he doesn't study he will have to repeat his grade." I immediately came to the conclusion that insouciance was another word for lazy. I thought that when  the sentence was describing the possible failure of the student, and how his insouciance would hurt him, the word was suggesting his lack of effort. When I looked up the actual definition online, it was: "Casual lack of concern; indifference." I didn't get the true meaning of the word, but using the context clues of the sentence, I managed to come up with a definition that sends almost the same message.
This method that I used to find the definition of insouciance involved my sense perception because I had to use my sense of sight to read the word and I had to use my mind to process the information. Once I had read the words on the page, I used my brain to interpret the sentence and think up a possible definition for it. I then delved into my memory to dig up my common sense and I used the conclusion I came up with to estimate a possible definition for insouciance. Context is truly essential in the area of sense perception, and it helps us dig out the clues that are sometimes hidden to us throughout our lives.
