Lies are an amazing phenomenon. This is an excellent multifunctional tool, with which you can avoid troubles, maintain good relationships with loved ones, and look better in the eyes of others. Moreover, you can successfully deceive both others and yourself. So is lying bad? The famous American writer, scientist and popularizer of science Sam Harris dissects the famous “immortal” sin under a microscope, revealing its negative aspects, and with the help of numerous examples proves to us: a lie, even the smallest one, is a weapon of terrible destructive power.
