the Other, (Capitalized) definition 2c from The Free Dictionary
often Other: A person or thing considered to represent or epitomize
difference or an outgroup. Used with the
The Other (Capitalized). I wish this reference explained it in simpler English, but here goes, from Wikipedia, other:
In phenomenology, the terms the Other and the Constitutive Other each
identify a cumulative, constituting factor in the self-image of a
person—the acknowledgement of being real. As such, the Other is
dissimilar to and the opposite of the Self, of Us, and of the Same.
Otherness, the characteristics of the Other, is the state of being
different from and alien to the social identity of a person and to the
identity of the Self. Another way of describing "The Other" is to
portray oneself at the centre of focus and "The Other" on the outside. (emphasis added)
Is your example a quotation from someone? It seems overstated, to put it mildly.
