The social order of pre-Revolutionary France was composed of three states: the 1st state was made up of clergymen, the 2nd state included all the nobility, and the 3rd state was formed by the rest of the population of France, including the peasantry, the bourgeoisie, and the city workers.
The experiences of the nobility and the bourgeoisie were very different during this period. The nobiity included around 1-2% of the population of the country. They were mostly exempt from taxes and for the most part, did not have a job. On the other hand, the bourgeoisie was a large percentage of the population, and carried a significant tax burden. This class was the most educated and wealthiest part of the 3rd State, and they resented the privileges of the nobles, in particular the tax exemptions. The conflict between these classes was a reason for the French Revolution.
This is a simple definition of his philosophy called Dualism.
Answer:
British mathematician William Bourne made some of the earliest known plans for a submarine around 1578, but the world’s first working prototype was built in the 17th century by Cornelius Drebbel, a Dutch polymath and inventor in the employ of the British King James I. Drebbel’s sub was probably a modified rowboat coated in greased leather and manned by a team of oarsmen. Sometime around 1620, he used it to dive 15 feet beneath the River Thames during a demonstration witnessed by King James and thousands of astonished Londoners. Unfortunately, none of Drebbel’s plans or engineering drawings has survived to today, so historians can only guess about how his “diving boat” actually operated. Some accounts say it submerged via a collection of bladders or wooden ballast tanks, while others suggest that a sloping bow and a system of weights were used to propel the boat underwater when it was rowed at full speed.
