El problema de la obediencia mal entendida...

Matt Damon reads from Howard Zinn's speech "The Problem is Civil Obedience" (November 1970) from Voices of a People's History on Vimeo.

Matt Damon, a lifelong friend of Howard Zinn and his family, read excerpts from a speech Howard Zinn gave in 1970 as part of a debate on civil disobedience.

This performance was part of "The People Speak, Live!" with Matt Damon and Lupe Fiasco at the Metro in Chicago, on January 31, 2012, produced by Voices of a People's History (www.peopleshistory.us) in collaboration with Louder Than a Bomb: The Chicago Youth Poetry Festival.

Here's what Howard Zinn writes about this speech in his introduction to the full piece in his book Voices of a People's History of the United States, written with Anthony Arnove and first published in 2004 by Seven Stories Press:

"In November 1970, after my arrest along with others who had engaged in a Boston protest at an army base to block soldiers from being sent to Vietnam, I flew to Johns Hopkins University in Baltimore to take part in a debate with the philosopher Charles Frankel on civil disobedience. I was supposed to appear in court that day in connection with the charges resulting from the army base protest. I had a choice: show up in court and miss this opportunity to explain — and practice — my commitment to civil disobedience, or face the consequences of defying the court order by going to Baltimore. I chose to go. The next day, when I returned to Boston, I went to teach my morning class at Boston University. Two detectives were waiting outside the classroom and hauled me off to court, where I was sentenced to a few days in jail. Here is the text of my speech that night at Johns Hopkins."

Time goes by...


“El tiempo no es oro, el oro no vale nada. El tiempo es vida” 

Ser dueños de nuestro tiempo y disfrutar de los momentos y la vida que conllevan está en la esencia de la felicidad . La felicidad no viene dada por la riqueza, sino por la libertad de decidir qué hacer con la vida.

¡Córcholis!


¿Has devuelto alguna vez una botella de en un restaurante, no siendo un snob pretencioso? Es posible que el motivo fuera que el vino tenía "olor a corcho" -  un olor a humedad y mal gusto característico.

Esto sucede habitualmente cuando el vino está contaminado con una molécula llamada 2,4,6-tricloroanisol (TCA), la principal causa de contaminación del corcho. El TCA aparece a partir de la degradación de los triclorofenoles (o TPA) que a su vez provienen de la unión de los fenoles del corcho con las partículas de cloro disueltas en el aire. Esta degradación tiene lugar en ambientes húmedos y es causada por una serie de hongos.

El tricloroanisol es responsable del olor y sabor a corcho del vino, bien por que el corcho no fue tratado adecuadamente durante su fabricacción o por que la botella no se ha mantenido en unas condiciones adecuadas de temperatura y humedad.

Un nuevo estudio realizado por investigadores japoneses ha llegado a la conclusión de que en realidad lo que se percibe no es el olor a TCA directamente, la TCA bloquea tu sentido del olfato y distorsiona tu capacidad para distinguir olores.

El hallazgo podría ayudar a la industria vinícola a mejorar sus productos y dar lugar a menos situaciones embarazosas frente al camarero.

Somos muy muy muy pequeños... no lo olvides nunca.


Before you judge other or claim any absolute truth consider that you can see less than 1% of the electromagnetic spectrum and hear less than 1% of the acoustic spectrum. As you read this, you are traveling at 220 km/sec across the galaxy. 90% of the cells in your body carry their own microbial DNA and are not “you.” The atoms in your body are 99.9999999999999999% empty space and none of them are the ones you were born with, but they all originated in the belly of a star. Human beings have 46 chromosomes, 2 less than the common potato. The existence of the rainbow depends on the conical photoreceptors in your eyes; to animals without cones, the rainbow does not exist. So you don’t just look at a rainbow, you create it. This is pretty amazing, especially considering that all the beautiful colors you see represent less than 1% of the electromagnetic spectrum.
