The (BLANK) philosophers believed that every aspect of life should be governed by strict and impersonal laws. PLEASE HELP ME
Makovka662 [10]

<u>Answer</u>: The <u>Legalists </u>philosophers believed that every aspect of life should be governed by strict and impersonal laws.

The Legalism is the third intellectual current that flourished in China before the unification by the Qin Dynasty. The three centuries before the unification were so rich in terms of political thought that is known as “The Golden Age of Chinese Philosophy” with “The Hundred Schools” of thoughts. Other famous schools in this period are Confucianism and Taoism.

The long period of war were times of great chaos and disorder. Profound changes happened during these three centuries – economical, military and social changes. A new administrative approach needed to arise and the Legalists were at the forefront of this innovation.  

Legalism is the most practical current of that period. Legalists would not focus on philosophical speculations, such as the evolution of the human nature, morality or divine will. Instead, they focus on how to achieve the goal of unification. Nothing, not even the past, could distract them of this goal. Because of that, they defended that the past doesn’t teach a thing and doesn’t shape the present or the future, but a radical change in the present is the only way to restructure the society. This change could only happen by “the rule of the law”, where individual morality of the ruled and the rulers are not taken into consideration. They believed that every aspect of life should be governed by strict and impersonal laws. Applying those is the radical change that would create a powerful government, able to coerce its subjects and install a rich state and a powerful army. In that scenario, the state has the ultimate authority and such power is given to it by means of military strength.

NEED HELP WITH THIS!! What do you believe should be Canada's role in the Syrian Crisis?
8_murik_8 [283]

Answer:

I believe that it should continue to welcome Syrian refugees and provide asylum to them in this time of crisis. Canada should also continue to support them financially until they are self-sufficient. Canada can speed up the process of resettling them by having a better plan about housing when they arrive and hiring more personnel.

It should contribute by volunteering with the United Nations to provide resources, like food and medical aid, to the refugees who are not resettled.

Canada should also help by sending diplomats and peacekeepers to help solve the root of the problem.
