  • Eyes Were Watching God Tea Cake
    1,278 words
    I enjoyed Their Eyes Were Watching God's grasp on imagination, imagery and phrasing. Janie's dialogue and vernacular managed to carry me along, slipping pieces of wisdom to me in such a manner that I hardly realize they are ingesting something deep and true. Their Eyes Were Watching God recognizes that there are problems to the human condition, such as the need to possess, the fear of the unknown and resulting stagnation. The book does not leave us with the hopelessness of Fitzgerald or Hemingwa...

    by David K. Phillips CLARIFIED When one mentions the term 'dating' it can produce, on the ambivalence continuum, feelings ranging from delightful bliss to genuine confusion or even aversion. Before I begin, let's bring some definition to this often nebulous term 'dating'. Webster defines dating simply as: 'to have social engagements with persons of the opposite sex'. In a casual sense, therefore, dating can certainly mean hanging out with the opposite sex for non-romantic purposes. Some of these...

    1,008 words
    A COMPARISON OF SMALL SCHOOL AND BIG SCHOOL SIZE SETUPS Until the mid- 1960 s, there was considerable agreement among sociologists and educational reformers that a substantial part of the differences in school performance by different students could be attributed to differences in the quality of schools they attended. Not only did the argument seem intuitively obvious, it also had considerable impressionistic evidence to support it. Students who attended run-down inner city schools, often with i...

Before the 1880 s there was no real conflict between the welfare of the American people and that of its business units. Tha...
