There, now you have been a little bit clearer on your proposed method of dealing with doubt (which does not necessarily lead to any answer to the original question of one's identity). And I couldn't disagree more with your perspective. For me, doubting is an essential part of what I am and how I build my worldview. It's not that I do not settle some doubts over time, but I don't want to have an artificial and deluded certainty about things which are usually more complex than simple binary options as you have used in your example. Doubting may be healthy in the sense that leads us to reevaluate our mindsets and attitudes towards life and existence in general, opening up great opportunities for self-improvement and personal development. Doubting is at the core of both the scientific method and the Cartesian philosophical approach to epistemology. Doubting invites us to constantly reassess what we believe in and why. Without doubt, we would be collectively stuck in a conformed status quo, an illusion of enlightenment. I urge everyone not to stop doubting, but to embrace it as an attitude of openness towards growth and better understanding.
