Hegel believed that the various philosophies of the past could be formulated into a comprehensive philosophy of the development of the human spirit. As a result of his work, the history of philosophy became an important field of study. A closed shop is a business establishment in which only union members may be employed. Either the union does all of the hiring or the employer does the hiring on the condition that all employees join the union within a certain period of time. A preferential union shop is slightly different from a regular closed shop because employees are only required to give preference to a union worker over a nonunion worker.
Greatness produces great effects.
One is not a great person whose actions in life leave the world as it was. A noted philosopher wrote that one of the lessons of history is that nothing is often a good thing to do and is always a clever thing to say. The distances between the earth and the stars are often measured in terms of light-years. A light-year is the distance that light travels in a year, at the rate of about 299,792 kilometers per second. This is about 9.46 trillion kilometers.
