Biotech Ethics and Advancement Essay Example for Free

Biotech Ethics and Advancement Essay Biotechnology: Of Ethics and Advancement Thousands of years ago, early man, like the rest of earths fauna and flora, was at the mercy of the elements; we relied on natures gratitude when it came to finding food and survival. As Charles Darwin would say, only the fittest could survive Mother Natures test. Eventually, however, a fully-evolved man turned the tide of the competition; we began to domesticate the once savage beasts we hunted and competed with like wolves and horses turning them into livestock and our own companions bred out of their natural ferocity, to grow our own food for our own and tart agriculture, and eventually we started to settle down into permanent communities. Man had transcended nature when the first steps of human civilization began to grow. Since then, man had crafted its own grand design for himself; the discovery of metals like Bronze and Iron, to the Pyramids of Egypt and Cities of Rome, and the rest, as they say, Is modern history. In the Modern world, we still have that said control, and with It we have now intrinsically used our knowledge to design nature herself In our Ideal Image. Technological Advancements have allowed us wield it as we pleasure. We can now edit Mother Natures work and remake It anew through our vast Interference with the body that is Science. The presence of GMOs (Genetically Modified Organisms), Dolly and all her Cloned brethren, and Real life Cyborg-Animals are Just samples of what weVe done to her. Eventually, because of this, someone Just had to say It: When will it be too much? When will we know when weVe gone too far? That Is where Ethics falls in, our man-made balance of whether or not, In the most basic sense, what we do Is right or wrong. Ethics has long been a question of how much more we can do to these once all natural things and make them artificially enhanced. When can we truly say that we, the masters have abused our power? One cannot mistake, however, that human alteration of natural things Is only a recent occurrence. Like I said, since the earliest ages of man we already tampered with nature as we sought. We turned once vlclous and wild wolves, through our process of selectively breeding the weaker ones, Into the loyal and lovable K9 friends we have today minus the genes of aggression. Pavlov strapped d own dogs to make psychological breakthroughs In condltlonlng. World War 2 scientists strapped bombs to dogs, dolphins, and even bats to assist them In fighting the enemy. Indeed, this tinkering of human hands has always been there. It now falls onto us people of today to see If things can still be set as Is. How much more can we do for our species own satisfaction? The Ethical question must always be present whenever we trod upon something as sensltlve as the condltlon of llvlng things. Animals, Ilke any other llvlng being, have xtremes in straining those rights to our needs. The uncertainty of Science itself shows that we cannot always control what happens to them come experiment time. The fear of abusing these innocent creatures is always on the minds of the very ethical/moral such as Animal Rights groups and such. Modern Genetics and Technology have sometimes crossed lines for the sake of advancement, such as taking away a creatures autonomy to turn them into natural robots. If this is truly how far Advancement has gone into sacrificing Lifes basic rules, then these righteous people really do have a reason to riot and protest.

Julius Caesar :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  In Julius Caesar Brutus displays the traits of a tragic hero through out this play but being a good person but makes an error in judgment, and when this error occurred it causes his own downfall. First off is that Brutus makes an error in judgment by joining the conspiracy to over throw Caesar. But the only reason that Brutus had joined was because his tragic flaw was honor; he lived his life on the guidelines of honor and loyalty. Now lastly Brutus had caused his very own downfall when after killing Caesar all of Rome has now turned against the conspirators. Those are some of the reasons that display Brutus is a tragic hero.   Ã‚  Ã‚  Ã‚  Ã‚  Brutus had joined the conspiracy for honor and for the good of Rome. Yet by joining this group his honor is really being put to the test because when he joined the conspiracy he pledged to take part in the murder of Julius Caesar. Brutus and Caesar are best friends, so now how is it honorable to kill one of your friends? But Brutus and the other conspirators had claimed that Caesar was just about to claim himself the king of Rome. When one has claimed themselves the king of Rome the people of Rome have the right to kill that person. So by saying this when the conspirators knew that Caesar was about to claim the thrown they strike and kill him. But another one of Brutus’ traits has now appeared, loyalty.   Ã‚  Ã‚  Ã‚  Ã‚  Loyalty and honor are the only tragic flaws that Brutus has but these are the reason that he has killed Caesar. Brutus had said that he had killed Caesar for the good of Rome and that his ancestors would have wanted this. Which is true that his ancestors had said that if any man were to claim themselves the king of Rome to kill them, but Caesar had never claimed himself king. The conspirators had only assumed that. So in reality by killing Caesar it wasn’t displaying loyalty and honor it was really showing stupidity. But Brutus’ tragic flaws are the real reason of his own downfall, as well as Rome’s.   Ã‚  Ã‚  Ã‚  Ã‚  Unfortunately Rome’s downfall was because Brutus had caused his own downfall. It first started when the conspirators killed Caesar, but what had made the situation worse was allowing Antony to speak at Caesar’s funeral. After the funeral the locals of Rome was so moved by Antony’s speech that they were in a blind fury and had to kill any conspirator that they had found, which ended up in the death of Cinna the poet.

The Colossus at Rhodes

Located on the island of Rhodes (off the coast of modern Turkey), the Colossus at Rhodes was a giant statue, about 110 feet tall, of the Greek sun-god Helios. Although finished in 282 BCE, this Wonder of the Ancient World only stood for 56 years, when it was toppled by an earthquake. Huge chunks of the former statue stayed on the beaches of Rhodes for 900 years, drawing people around the world to marvel at how man could create something so enormous. Why Was the Colossus of Rhodes Built? The city of Rhodes, located on the island of Rhodes, had been under siege for a year. Caught up in the heated and bloody battle between the three successors of Alexander the Great (Ptolemy, Seleucus, and Antigonus), Rhodes was attacked by Antigonus’ son, Demetrius, for supporting Ptolemy. Demetrius tried everything to get inside the high-walled city of Rhodes. He brought 40,000 troops (more than the entire population of Rhodes), catapults, and pirates. He also brought a special corps of engineers that could make siege weapons specially geared to break into this particular city. The most spectacular thing these engineers built was a 150-foot tower, mounted on iron wheels, that hosted a powerful catapult. To protect its gunners, leather shutters were installed. To protect it from fireballs hurled from the city, each of its nine stories had its own water tank. It took 3,400 of Demetrius’ soldiers to push this mighty weapon into place. The citizens of Rhodes, however, flooded the area around their city, causing the mighty tower to wallow in mud. The people of Rhodes had fought back valiantly. When reinforcements came from Ptolemy in Egypt, Demetrius left the area in a hurry. In such a hurry, that Demetrius left nearly all of this weapons behind. To celebrate their victory, the people of Rhodes decided to build a giant statue in honor of their patron god, Helios. How Did They Build Such a Colossal Statue? Funding is usually a problem for such a large project as the people of Rhodes had in mind; however, that was easily solved by using the weapons that Demetrius had left behind. The people of Rhodes melted down many of the leftover weapons to get bronze, sold other siege weapons for money, and then used the super siege weapon as the scaffolding for the project. Rhodian sculptor Chares of Lindos, the pupil of Alexander the Great’s sculptor Lysippus, was chosen to create this huge statue. Unfortunately, Chares of Lindos died before the sculpture could be completed. Some say he committed suicide, but that is probably a fable. Exactly how Chares of Lindos constructed such a gigantic statue is still up for debate. Some have said that he built a huge, earthen ramp that got bigger as the statue got taller. Modern architects, however, have dismissed this idea as unpractical. We do know that it took 12 years to build the Colossus of Rhodes, likely from 294 to 282 BCE, and cost 300 talents (at least $5 million in modern money). We also know that the statue had an exterior that consisted of an iron framework covered with bronze plates. Inside were two or three columns of stone that were the main supports for the structure. Iron rods connected the stone columns with the exterior iron framework. What Did the Colossus of Rhodes Look Like? The statue was to stand about 110 feet high, on top of a 50-foot stone pedestal (the modern Statue of Liberty is 111 feet high from heel to head). Exactly where the Colossus of Rhodes was built is still not certain, although many believe it was near the Mandraki Harbor. No one knows exactly what the statue looked like. We know that it was a man and that one of his arms was held aloft. He was likely naked, perhaps holding or wearing a cloth, and wearing a crown of rays (as Helios is often portrayed). Some have guessed that Helios’ arm was holding a torch. For four centuries, people have believed that the Colossus of Rhodes was posed with his legs spread apart, one on each side of the harbor. This image stems from a 16th century engraving by Maerten van Heemskerck, which depicts the Colossus in this pose, with ships passing under him. For many reasons, this is very likely not how the Colossus was posed. For one, legs open wide is not a very dignified stance for a god. And another is that to create that pose, the very important harbor would have had to have been closed for years. Thus, it is much more likely that the Colossus was posed with legs together. The Collapse For 56 years, the Colossus of Rhodes was a wonder to see. But then, in 226 BCE, an earthquake struck Rhodes and toppled the statue. It is said that the Egyptian King Ptolemy III offered to pay for the Colossus to be rebuilt. However, the people of Rhodes, after consulting an oracle, decided to not rebuild. They believed that somehow the statue had offended the real Helios. For 900 years, huge pieces of the broken statue lay along the beaches of Rhodes. Interestingly, even these broken pieces were huge and worth seeing. People traveled far and wide to see the ruins of the Colossus. As one ancient writer, Pliny, described after seeing it in the 1st century CE, Even as it lies, it excites our wonder and admiration. Few people can clasp the thumb in their arms, and its fingers are larger than most statues. Where the limbs are broken asunder, vast caverns are seen yawning in the interior. Within it, too, are to be seen large masses of rock, by the weight of which the artist steadied it while erecting it.* In 654 CE, Rhodes was conquered, this time by Arabs. As spoils of war, the Arabs cut apart the remains of the Colossus and shipped the bronze to Syria to sell. It is said that it took 900 camels to carry all that bronze. * Robert Silverberg, The Seven Wonders of the Ancient World (New York: Macmillan Company, 1970) 99.
