The gesture is far from being insignificant in the expression of our social relations and because of its active importance during our exchanges, of the induced meaning that it evokes, it must deserve all our consideration, just like the medical profession which accompanied during this pandemic.

In the beginning, long before the word, was the gesture. And as Michel Guérin writes in “Philosophy of gesture”, the gesture attests to an “animal wanting to say”.
For Ernst Cassirer too, it is the gesture that makes a sign, which would be at the origin of language.
The gesture is part of our method of communication, it maintains a close relationship with our speech, it puts the signifier into image and mimics the signified. He invites himself into the conversation to bring color, depth and identity to our words.

In GESTURES the hand is not represented as a prehensile member, capable of grasping, manipulating, making, writing, touching. She is represented in her gestural role, that which signifies.

Still according to Michel Guérin, it would even seem that the gesture would perhaps be nothing other than the very movement of thought.
Gesture thus contributes, in relation to words, to the construction and transmission of meanings. It brings additional ideas to those evoked by the speech, and promotes the production of the latter. It participates in the effort of verbalization in redundancy or in complementarity with verbal expression.
