摘要：Ethics without doubt is an issue in every scientific field. Questions on ethics are not merely questions onthe responsibility of one or two specific individuals, but rather as what have been defined accurately byImmanuel Kant in Critique of Practical Reason – as question of all humanity as a thinking creature and thefreedom of choice on, “what should I do”. From Kant’s definition, we may infer that if human can not think andnot free in determining their choice, it would be almost impossible to hope for moral responsibility. However thisarticle does not mean to give a full and historical description on ethics, but a sketch on discourse ofcontemporary ethics which is represented by two famous philosophers, Jürgen Habermas from the tradition ofCritical Theory from Frankfurt School, dan Richard Rorty with “Neo-Pragmatism”. Habermas proposes“discourse ethics” while Rorty proposes ethic concepts through his “liberal-ironists”. It is hoped that theassembly of readers may gain an insight of the unavoidable ethics problems since every ethical position must betheory laden and the theory itself has historical characteristics (the characteristics, origin and historical contextof the schools behind it). Therefore ethics is a neverending reflection although it has been started from 2500years ago. Ethics invites us from specific sciences to enter its general discourse which unavoidably allencompassingin its nature.
