deception and truth telling

I think that deception is generally bad but I agree with the statement that sometimes lying is not morally debilitating if no harm is done "white lies". Lying is necessary for the area of knowledge called knowledge by description. When people are describing things to other people or teaching them about it then sometimes deception is necessary. Like the artist who staged the photo to teach people how things would normally look, he was being honest about what he had seen but he was using deception when he said that the photo was accurate. Plus when people describe things that tend to embellish to get a point across which could be another form of deception.
