Answer by A Quora admin: (Ed. note: I have no idea why Quora gives “A Quora admin” attribution for my answers there, when I share one to this blog – but I’ve asked my very first question there to find out! I’ll let you know.)
In psychoanalysis, the term “ego” refers to “he part of the mind that mediates between the conscious and the unconscious and is responsible for reality testing and a sense of personal identity.” This is different from the unmediated, childish, self-centered notion many people have in mind when they talk about someone (else’s) “ego.” In philosophy, it refers to a “a conscious thinking subject.”
By those definitions of the word, no – one absolutely cannot have an opinion separate from their ego. An “opinion” is defined as “a view or judgment formed about something, not necessarily based on fact or knowledge.” Thus, an opinion is uniquely your own (even if similar opinions are held by many others), and is inextricably tied to your ego.
