There are no dangerous thoughts; thinking itself is dangerous.- Hannah Arendt When I heard this I immediately wanted to know why she thought that. How can something that merely goes on inside your head be dangerous. Maybe because what you think or the way you think decides on how you are going to act or how you are not going to act? Is it dangerous to the thinker him/herself or to society? Are all kinds of thinking or thoughts dangerous, i.e. rational, calculative thinking, meditiative thinking? I know this is hard to discuss without getting to abstract but if somebody can help me make sense of all off this I would appreciate it. I also think examples might be needed to really ground a discussion in reality but some level of abstract thinking might also be necessitated to help us get at the underlying ideology. I know that thinking can sometimes get me lost in an abstract world of my own creation and alienate me from the world or just make me generally pretty paranoid if not distrustful, but I was wondering if you all think that your own thoughts may be dangerous. I guess an example might be that someone's negative thinking might lead them to suicide. That can be considered dangerous. I appreciate any feedback on this. I think it is one of the most important questions I have ever asked. It relates to another Hannah Arendt quote: "To think and to be fully alive are the same."
