You shouldn’t Judge a book by its cover.
This is a phrase to which I take exception, and I do not know why this phrase has become so renowned as it seems so false to me. I am not talking about this phrase in its literal sense with regard to books; however, I still think it is false when talking about literal books. I have a degree in nutrition and food science, and there are thousands of books that I can judge by the cover and know they are trash and not worth my time. Time is a resource I do not wish to waste, so I will judge some books by their cover to save it.
Onto the more philosophical application of the phrase. The cover is all the information you have about someone whom you’ve never seen before. If you have already seen someone or something, you have already judged them/it at least once. One extreme example I have to evaluate this involves children or vulnerable people. Should you allow a child to interact with any random person as you should not judge them by their cover, or should you judge them and base your decision on all the visual cues you have?
As an adult I judge people, rightly or wrongly – here I am arguing that it is rightly– by their cover. If I am walking down the street and see some drunk men quarrelling, you can safely assume that cover will be judged harder than an autobiography by a reality TV star.
Why I think this phrase still has some credibility is that invariably whenever you meet someone, they are a good person. Should you judge a person as good before you’ve gotten to know someone? And is It even possible to not judge someone? I doubt it.
In fact, I would go further than saying you should judge a book by its cover; you continually judge by the cover. As you gain information, you should continually re-adjust your judgement as people can and do change.
There are a number of reasons as to why I do not understand this phrase and therefore, do not take it seriously. I imagine this could be a contentious issue and my opinion may be somewhat naive, so please educate me.
Apparently the phrase was first published in the mid 18th century, and frankly, that’s where it should have stayed.
