Read this sentence from the "Influence of Lincoln" and answer the question. I realized that no one among his own countrymen had been able to interpret Lincoln’s greatness more nobly than this Oxford scholar had done, and that vision and wisdom as well as high motives must lie behind every effective stroke in the continuous labor for human equality.

In at least one hundred words, discuss how the italicized part of the sentence could be the thesis for "Influence of Lincoln." Include at least one reason why it could not be the thesis. Use examples from the chapter to support your reasoning.

I got this question on Odysseyware and this was the answer I used...Hope this helps!!!

The italicized part of the sentence could be the thesis for "Influence of Lincoln" because it brings Addam's idea together that Lincoln was a remarkable person, with much wisdom, intellect, perception, and most importantly, high morals to be capable of progressing and protecting a nation's democracy. It idealizes the point that Lincoln was no ordinary man, and that no ordinary man has the power to make an impact on society as strong as Lincoln did, if they do not portray the same or similar characteristics. 
It may not be a thesis however, since it is embedded within one of her many stories in the chapter. A thesis should typically be placed towards the beginning of the chapter, to summarize the main points, and this sentence was towards the end of the chapter.
