Machiavelli saw history in general as a way to learn useful lessons from the past for the present, and also as a type of analysis which could be built upon, as long as each generation did not forget the works of the past. In "Discourses on Livy" Machiavelli discusses what can be learned from roman period and many other eras as well, including the politics of his lifetime. This is a work of political history and philosophy written in the early 16th. The title identifies the work's subject as the first ten books of Livy's Ab urbe condita, which relate the expansion of Rome through the end of the Third Samnite War in 293 BC. Niccolò di Bernardo dei Machiavelli (1469 – 1527) was an Italian diplomat, politician, historian, philosopher, humanist, and writer. He has often been called the father of modern political science. He was for many years a senior official in the Florentine Republic, with responsibilities in diplomatic and military affairs. He served as a secretary to the Second Chancery of the Republic of Florence from 1498 to 1512, when the Medici were out of power.He wrote his most well-known work The Prince in 1513, having been exiled from city affairs.

How can scientific knowledge be translated into political change? Ozone Discourse examines the first global environment treaty, the Montreal Protocol and its subsequent revisions, which was a highly effective collaboration among scientists, policymakers and activists. The treaties were the work of a small group of experts who, without conventional political or economic resources, were able to persuade most of the world's nations to agree to reduce and then eliminate chlorofluorocarbons. These experts used their understanding of atmospheric science to supplement the policymakers' short-term perspective with a wider, intergenerational timeframe characteristic of global environmental problems. Litfin argues that the discipline of international relations requires a broader conception of power in order to accomodate the knowledge-based problems such as environmental degradation.

In the past, the distinctions between art and science weren't as clear-cut as they are today, and philosophers, researchers, and artists often shared insights and ideas. It was in that heady atmosphere that Sir Joshua Reynolds first rose to prominence, initially through his "Grand Style" paintings, but later for his work as a promoter of scientific research and the president and co-founder of the famed Royal Society. This text outlines some of Reynolds' most groundbreaking ideas about art, scholarship, and the intersection between the two.

The Discourses of Epictetus Epictetus - The books did not have a formal title in ancient times. Although Simplicius called them Diatribai other writers gave them titles such as Dialexis , and Homiliai . The modern name comes from the titles given in the earliest medieval manuscript: "Arrian's Diatribai of Epictetus" . The Greek word Diatribai literally means "informal talks".As to the date, it is generally agreed that the Discourses were composed sometime in the years around 108 AD. Epictetus himself refers to the coins of Trajan, which shows he was teaching during that reign. Arrian was suffect consul in around 130, and since forty-two was the standard age for that position, he would have been at the right age of around twenty in 108. Furthermore the "commissioner" of the "free cities" to whom Discourse iii. 7 is addressed is thought to be the same man Pliny the Younger addresses his Letter viii. 24a letter which has been dated to around 108.
