18th Century European Enlightenment Essays - Age Of Enlightenment

18th Century European Enlightenment Essays - Age Of Enlightenment 18th Century European Enlightenment The Enlightenment is a name given by historians to an intellectual movement that was predominant in the Western world during the 18th century. Strongly influenced by the rise of modern science and by the aftermath of the long religious conflict that followed the Reformation, the thinkers of the Enlightenment (called philosophes in France) were committed to secular views based on reason or human underezding only, which they hoped would provide a basis for beneficial changes affecting every area of life and thought. The more extreme and radical philosophesDenis Diderot, Claude Adrien Helvetius, Baron d'Holbach, the Marquis de Condorcet, and Julien Offroy de La Mettrie (1709-51)advocated a philosophical rationalism deriving its methods from science and natural philosophy that would replace religion as the means of knowing nature and destiny of humanity; these men were materialists, pantheists, or atheists. Other enlightened thinkers, such as Pierre Bayle, Voltaire, David Hume, Jean Le Rond D'alembert, and Immanuel Kant, opposed fanaticism, but were either agnostic or left room for some kind of religious faith. All of the philosophes saw themselves as continuing the work of the great 17th century pioneersFrancis Bacon, Galileo, Descartes, Leibnitz, Isaac Newton, and John Lockewho had developed fruitful methods of rational and empirical inquiry and had demonstrated the possibility of a world remade by the application of knowledge for human benefit. The philosophes believed that science could reveal nature as it truly is and show how it could be controlled and manipulated. This belief provided an incentive to extend scientific methods into every field of inquiry, thus laying the groundwork for the development of the modern social sciences. The enlightened underezding of human nature was one that emphasized the right to self-expression and human fulfillment, the right to think freely and express one's views publicly without censorship or fear of repression. Voltaire admired the freedom he found in England and fostered the spread of English ideas on the Continent. He and his followers opposed the intolerance of the established Christian churches of their day, as well as the European governments that controlled and suppressed dissenting opinions. For example, the social disease which Pangloss caught from Paquette was traced to a "very learned Franciscan" and later to a Jesuit. Also, Candide reminisces that his passion for Cunegonde first developed at a Mass. More conservative enlightened thinkers, concerned primarily with efficiency and administrative order, favored the "enlightened despotism" of such monarchs as Emperor Joseph II, Frederick II of Prussia, and Catherine II of Russia. Enlightened political thought expressed demands for equality and justice and for the legal changes needed to realize these goals. Set forth by Baron de Montesquieu, the changes were more boldly urged by the contributors to the great Encyclopedie edited in Paris by Diderot between 1747 and 1772, by Jean-Jacques Rousseau, Cesare Beccaria, and finally by Jeremy Bentham, whose utilitarianism was the culmination of a long debate on happiness and the means of achieving it. The political writers of the Enlightenment built on and extended the rationalistic, republican, and natural-law theories that had been evolved in the previous century as the bases of law, social peace, and just order. As they did so, they also elaborated novel doctrines of popular sovereignty that the 19th century would transform into a kind of nationalism that contradicted the individualistic outlook of the philosophes. Among those who were important in this development were historians such as Voltaire, Hume, William Robertson, Edward Gibbon, and Giambattista Vico. Their work showed that although all peoples shared a common human nature, each nation and every age also had distinctive characteristics that made it unique. These paradoxes were explored by early romantics such as Johann Georg Hamman and Johann Gottfried von Herder. Everywhere the Enlightenment produced restless men impatient for change but frustrated by popular ignorance and official repression. This gave the enlightened literati an interest in popular education. They promoted educational ventures and sought in witty, amusing, and even titillating ways to educate and awaken their contemporaries. The stories of Bernard Le Bovier de Fontenelle or Benjamin Franklin, the widely imitated essays of Joseph Addison and Richard Steele, and many dictionaries, handbooks, and encyclopedias produced by the enlightened were written to popularize, simplify, and promote a more reasonable view of life among

Dry Thunderstormsâ€Their Causes and Dangers

Dry Thunderstorms- Their Causes and Dangers A dry thunderstorm is one that produces little or no rain. While it might seem like a contradiction in terms to have a thunderstorm without precipitation, its actually quite common in areas of the western United States where the heat index can be very high, particularly in late spring and early summer months with low humidity.   How a Dry Thunderstorm Occurs A thunderstorm can be called dry  when temperature and heat gather  below the cloud cover, called the aerial canopy. It will rain, but the rain and other forms of precipitation never manage to reach the ground. The storms rain and any moisture evaporate as they fall and near the earth. In meteorology, this event is called virga.   The #1 Natural Cause of Wildfires Dry thunderstorms  are often the culprits behind massive wildfires when lightning ignites a dry fuel source on the ground during  fire weather  season, which is the hot summer months. Although theres no rain, at least at ground level, these storms still pack plenty of lightning. When lightning strikes in these arid conditions, its called dry lightning and wildfires can easily erupt. Vegetation and flora are often parched and readily ignitable. Even when a light rain does manage to survive and hit earth, this moisture is typically nowhere near enough to have any effect on the fires. These storms can additionally produce severe, strong winds called microbursts that can whip the fires about and shift them, making them hard to battle. The Potential for Dust Storms Dry microbursts are another weather phenomenon associated with dry thunderstorms. When  precipitation evaporates as it nears ground level, this cools the air, sometimes radically and suddenly. This cooler air is heavier and it tends to plummet quickly to earth, creating strong winds. And remember- theres little to no associated rain and moisture here. Thats already evaporated, causing the microburst in the first place. These winds can kick up dust and other debris in arid regions, resulting in sand and dust storms. These storms are called ​haboobs  in the western states that are prone to them.  Ã¢â‚¬â€¹Ã¢â‚¬â€¹ Staying Safe in a Dry Thunderstorm   Dry thunderstorms can typically be predicted well in advance of the storm so officials can warn residents in vulnerable areas. Incident meteorologists, called IMETs, go on full alert. These specially-trained meteorologists look for the fuels that will help a wildfire spread. IMETs have training in microscale forecasting, fire behavior, and fire operations. They also act as managers who can help coordinate control efforts. Decisions are made on how to best control and contain wildfires based on  predictions of wind speed and direction. Even if you do not receive an alert that the weather in your area is prime for a dry thunderstorm, youll know because you should hear thunder. If rain doesnt arrive before the thunder, simultaneously, or shortly thereafter, a dry thunderstorm- and the potential for fire- is probably imminent. If theres thunder, there  will  be lightning, although the severity of the lightning can vary depending on the storm system. As with any storm, seek shelter if youre outdoors.
