A philosopher by nature who has little knowledge in the actual field of philosophy.
Do I have the right to call my self a philosopher then? If a philosopher refers to the practice or process of thinking philosophically, then yes; if a philosopher refers to the amount of knowledge acquired in the field of philosophy, then no.
Either ways, a "right" is an interchangeable matter governed by time & location. For now, I have the right to speak, and I speak through my writings.
