Abstract
The question that interests us here can be thus formulated: what is the place of thinking in the structure of the ethical practice? In other words, how does that “mind’s activity”, commonly opposed to the action, lies itself in the practical reasoning capable of signing an ethical sense to the action? Whatever is the relation that we can establish between the thinking and the good, between the aiming of the good and the act that makes it effective, we can ask ourselves if the same happens with their opposites: the lack of thought and the evil. Such question leads us, finally, to the limits of the ethical action as such. However, if it is necessary to well think to well act, can we say that the lack of thought or discernment causes the bad action? Two authors will be mainly mobilized to this study: Hannah Arendt and Aristotle
