Turchet didn't just want to teach you how to spot a liar; he wanted to teach you how to understand the biography of a body. His central thesis, detailed in The Secrets of Body Language (original French title: Les Secrets du Langage Corporel ), is radical:
Body language is a universal language that transcends cultural and linguistic barriers. It can convey emotions, intentions, and attitudes, often unconsciously. Our body language can reveal our true feelings, even when our words say otherwise. For instance, a person may say they're happy to see you, but their crossed arms and avoiding eye contact may suggest otherwise. By understanding the secrets of body language, you can become more aware of your own nonverbal cues and learn to interpret those of others. the secrets of body language philippe turchet pdf
