Gettier Problem

Am I the only one who thinks this week's lesson was tough! I give myself an A for effort. (Lol) When looking at all of the proposed solutions at which was given to us, Getter Problem seems to resemble the definition of justification. My understanding of a mistaken belief defines the accuracy with which justification must be engaged. Looking at the first solution; If I had to be at work at 2:10 in order to get outside in time to leave for work in time that would allow me to leave the house before that time approaches, and I know I would be late and disciplined for coming into work late I would not be justified in thinking the clock was correct in order to believe it was 2:30.

Justification is basically an external system of judgment as to the sufficiency of what we believe, not its correctness, but only the legitimacy of holding the belief. It's valuable that we hold high expectations for what we believe is knowledge.

The instructor went over epistemic humility which in definition means "I need to recognize the limitations of my cognitive abilities", or knowing when or how to appropriate our knowledge to others.
