Dada in Tzara's Manifesto is said to mean nothing he talks badly about other poets who write simply on one spectrum Sad poetry and the other who just write love poems he scolds them for their selling out to the bourgeoisie for a promise of good meals wine and a comfortable living. Tzara means by this that his movement speaks to a much bigger audience because simply it is not made for a specific one. This is evident in the changes in language in the Cabarets and the addition of some German, Italian, and french works. THey even include Marinetti's works in the first dada movement. So even though he speaks of releasing old things like the futurist he doesnt refuse to learn from them. He doesnt hate science because he like it innovation but he refuses its order. He believes in no perfect truth but he still wants to make art but in a different way than others. YOU see this in some of the poems especially Emmy Hennings Song to the Dawn and maybe the last flight they are both very ambigious and kind of contradictory at first in maybe the last flight the girl seems estactic and excited and then the next day she dies or is embarrased by seeing the man again. I think this is a perfect example of what Tzara talked about in the manifesto.
