I have made a few corrections, in the first and second paragraph
the tense needs to remain constant- i went with the beginning present tense,
i would say that the essay just needs to be put in the active voice and take out the qualifications, could, maybe possibly, you should state your opinion without undermining it with these unnecessary words
the active tense will create a more concise, nonwordy paper. When we write, we tend to speak differently than how we speak. If you think more about how you would express it in a conversation you will more likely use the active tense, and omit unnecessary words
I did not change all the sentences but i think its the same issue throughout
A mother's love is one of a kind for each individual, as mothers bring their own children to the world and nurture them till adulthood.
to
As mother's rear and nurture their children, a mother's love is one of a kind.
The unconditional love mothers feel towards their children is a perpetually unique notion, which tends to be idealized in literature.
to
The unconditional love of a mother tends to be idealized in literature.
(it is unclear what is unique about this?) and why is it perpetual?) the sentence seems stronger with out this, though maybe i am missing your point.
[quote=chocole][quote=chocole]However, this positive attitude could be perverted as the subversion of this nature can occur during distressed times, as external values begin to displace the maternal instinct.
(using "could" weakens your argument, this qualification undermines your argument_
However the idealization of a mother's love is an unreasonable expectation and provides a disservice. The subversion of this nature can occur during distressed times, as external values begin to displace the maternal instinct.
