Answer:
I'm no good at geometry. Whenever I answer questions wrong in class, the teacher looks at me like I'm stupid and other students laugh at me
Explanation:
As developed by Charles Horton Cooley in 1902, the looking-glass self is a social psychological concept suggests that a person's self "judgement" is developed out of society's interpersonal interactions and the perceptions of others. In other words stating that we develop our self based on the judgements of others. This is reflected in the statement above
where the student believes he is "no good at geometry" because others laugh and believe he is "no good at geometry"
This is of course a very complex question that does not have a definitive answer, but 1850s would be a good decade to start counting as "Modern". This was a decade of the telegraph and Darwin's The Origin of Species.
