Matt Lamkin’s “A Ban On Brain-Boosting Drugs is Not the Answer” first appeared in Chronicle of Higher Education in 2011. In this essay Lamkin aims to convince his reader not to deter improper conduct with threats, but to encourage students to engage in the practice of education. Lamkin tells us “If colleges believe that enhancing cognition with drugs deprives students of the true value of education, they must encourage students to adapt that value as their own” (642). Appeal to logic, consistency, and compare/contrast are techniques Lamkin skillfully uses to create a strong effective essay.

1. Eighner organizes his essay by breaking down how and why scavengers do what they do to survive. He begins his essay with how he became a scavenger and follows that with how to scavenge the best, safest way possible. He communicates how to choose the right dumpsters to dive into, how to determine if food is edible, and whether items are worth holding onto. I believe Eighner chose this type of organization throughout his essay to ease readers into the idea of scavenging through dumpsters. I feel like Eighner is almost trying to convince reader that’s scavenging through dumpster is not that bad, so if he shed the activities in a positive
There is not a great deal of context that is crucial to understanding the essential themes of the Meno, largely because the dialogue sits nearly at the beginning of western philosophy. Socrates and Plato are working not so much in the context of previous philosophies as in the context of the lack of them. Further, this is very probably one of Plato's earliest surviving dialogues, set in about 402 BCE (by extension, we might presume that it represents Socrates at a relatively early stage in his own thought). Nonetheless, in order to understand the aims and achievements of the dialogue, it helps to keep in mind some details about this lack of previous philosophies.
