P1) Over a twenty four hour period, the sun and planets can be seen moving from the east direction to the west direction. P2) The earth could not be moved by two motions like other planets, because there is no variance in the rising and setting of the heavens. P3) If the Earth moved, a dropped object would travel in the direction that the earth itself is moving and would be slowed down by said motion. Scientific experiments have exhibited that objects travel the same distance no matter what way they are launched or projected. However, the objects must be projected with equal force. P4) The natural motion of all things is towards the center of the earth. When an object is dropped from any …show more content…
It is invalid because Salviati detects a logical fallacy in the Aristotelian view. When Salviati asks Simplicio how he proves that the stone fell in a straight path beside the towers, Simplicio says that he can prove it “by the senses”. Salviati goes on to explain that the Aristotelians are committing the logical fallacy of petitio principii, which can be translated to “begging the question”. This means that the Aristotelians are assuming the conclusion of the argument in their premises. The fact that we perceive the stone falling straight down the side of the tower does not prove that it is the actual motion of the stone unless we first assume that the earth is stationary. The invalidity of the argument concludes that the argument is also …show more content…
I think the Copernican point of view is best because it clearly explains the changing of the seasons, the constellations changing, the phases of the moon, the changing tides, and the viewing of the different planets. I believe it the strongest proof of the rotating earth is the changing of the seasons and the viewing of the different planets. How can you explain that you can only view planets in certain places at different times? If the earth was stationary, only one area of the world would be able to see a certain planet. However, the planet may not appear for a certain part of the world for a period of time. As for the seasons, How can we explain cold spells and warm spells if the earth stays in one place and the sun rotates around us once every 24 hours? The only way this would make sense is if the earth moved farther from the sun. Therefore, people should accept the Copernican
