I finally felt like I could title a Heidegger reading as being faithful. I'm starting to put his stuff together a lot better and am better at piercing the thick veil of his specialized language. In essence, Heidegger goes to great lengths to explain experiences that we have too such a degree that we get to peek into what it's like to be something we already are.
As Heidegger says, conscience is a call. A call implies that there is a call and a caller. Further, a call is an attempt at communication to compel an action. More terms are necessary here to explain what I think Heidegger is trying to explain. We have the Dasein (there-being) which seeks to speak to the self, the they-self which is the Other outside the self, and the Self which seems to me to be the thing that struggles to be comfortable in the world.
When we hear the call of conscience, we are typically engaged with the they-self. We here the call and it beckons us to consider its voiceless and wordless message of showing us where we have or will falter. Through the call of the conscience we recognize our potential for being authentic. If we are able to suppress the they-self influence over us and act according to Dasein, we can act authentically. Unfortunately, to me at least, it seems that Heidegger says we have found the habit of taking refuge in the they-self altogether too much and departing from the they-self to act authentically is a scary process.
