I see Gadamer's philosophy in Truth and Method as radar.
An event happens we get certain signals. Based on these signals we send out a response (our response is heavily laden with language that plays us). This response hits the event and we get returned feedback. We recalculate and send back another response, this time we get a slightly nuanced feedback. We repeat this "dialogue" and eventually we get a sense of the form of this "thing".
The next time an event "like this" happens, based on the historicity of our being we know to engage it such manner. Yet, this case shows something different of the "thing" and so our knowledge of the thing grows yet is always revealing previously hidden realms.
Am I way off here?
