Rosa Luxemburg was a political theorist of the working class movement and the leader of German Social Democracy. Altough she was deeply involved in the political events of her period, in the context of that inhuman and exploiting society, Rosa never resigned the pursuit of happiness. From her prison, where she was confined many times because of her involvement in the propaganda against the war, she continued to speak about the importance to be and remain humans. So, while she goes with studying botany, she likes to look at the clouds and the lovely titmice from the window of her cell. She knows she may venture her life, if necessary, but she feels the possible death thought as nothing more than a «pensiero atroce» (a nasty thought).
