As everyone knows, the fragility is the capacity to be broken, damaged or to annihilated. It is opposed to the solidity, to the stability, and in a sense maybe, to the reliability. To be held in this definition, the fragility could be considered, not as a quality that some. Beings or certain things possess, but rather as a line common to all which exists in the world, the vulnerability, the solitude, the precariousness, the instability, it is that I tried to look through my research. Workshop with Reiner Riedler.
