The word “sincere” comes from the Latin sin cirus meaning without beeswax as referred to pure honey. Later, this word was used for a person who speaks their mind, who doesn’t fool others.
One can be sincere without telling the truth only if they are unconsciously wrong at the start. In comparison, a liar doesn’t believe their own lie, unless repeated all the time, a perversion called mythomania.
Generally speaking, orators are not sincere: they speak to provoke a certain reaction and not to communicate their thoughts. Therefore, sincerity’s requirements are mostly transparency and sometimes authenticity. For sociability causes, one tends to wear a mask for protection or for manipulation; society often tells us to be less sincere to fit in.
Are we all mythomania?
Mythomania is an abnormal or pathological tendency to exaggerate or tell lies.
If we take this classical definition, can it be adapted to our virtual social behavior on social media? Is an airbrushed photo or a well enhanced profile considered as mythomania? Let’s face it, most people won’t admit they used Photoshop for their photos, not they would admit that they lied about their profiles. Obviously, there is a worse example like identity theft. Is the thief a mythomaniac or aren’t we all?
The paradox is we have all been raised for higher moral values such as sincerity and authenticity. We all went on retouching innocently our photos and marketing ourselves on a larger identity. Maybe the question worse asking here is: are we all, not mythomaniac, but schizophrenic? What if the latters are both social disorders? Are certain types of societies the creator of those disorders, better known as psychological issues?
The easiest way to answer would be to say they are psychosocial. Let’s go further and say they are epigenetic, genetically wired by our culture to be mythomaniac. Epigenetic studies the impact of culture (social behavior and nutrition) on our genes. Would it be an option to explain collective disorders?
