“We Dadaists are often told that we are incoherent, but into this word people try to put an insult that it is rather hard for me to fathom. Everything is incoherent… There is no logic… The acts of life have no beginning and no end. Everything happens in a completely idiotic way. That is why everything is alike. Simplicity is called Dada. Any attempt to conciliate an inexplicable momentary state with logic strikes me as a boring kind of game… Like everything in life, Dada is useless… Perhaps you will understand me better when I tell you that Dada is a virgin microbe that penetrates with the insistence of air into all of the spaces that reason has not been able to fill with words or conventions.”
