After reading the Social Theory reader about Marx, there was a reference to animals and laborers and human beings as laborers that I found to be somewhat innaccurate. In the last section, "Marx: Economic and Philosphical Manuscripts", it was written that "they [animals] produce only their own immediate needs or those of their young; they produce one-sidedly, while man produces universally..." It continues, but I don't think that claim holds true. Animals produce for us, and it may sound silly, but they don't know they are doing us favors by providing for us food, clothing, and even comfort (in pets, etc.) Therefore, in the modern world, would Marx's theories have to be re-examined? To fit with modern times and the way that humans now see much more importance in animals. They are used as testing for medicines, vaccines, etc. That was never done before, but we must think of those things now-a-days.
