If I shout: Ideal, Ideal, Ideal Knowledge, Knowledge, Knowledge, Boomboom, Boomboom, Boomboom I have recorded fairly accurately Progress, Law, Morals… - Tristan Tzara

Some people think they can explain rationally, by thought, what they think. But that is extremely relative... There is no ultimate Truth. The dialectic is an amusing mechanism which guides us / in a banal kind of way / to the opinions we had in the first place. Does anyone think that, by a minute refinement of logic, he has demonstrated the truth and established the correctness of these opinions? Logic imprisoned by the senses is an organic disease

A manifesto is a communication made to the whole world, whose only pretensions is to the discovery of an instant cure for political, astronomical, artistic, parliamentary, agronomical and literary syphilis. It may be pleasant, and good-natured, it's always right, it's strong, vigorous and logical.
Apropos of logic, I consider myself very likeable.

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.
