Final answer:
John Locke wrote the Second Treatise of Government and supported the concept of popular sovereignty, believing that natural law was given to humans by God, and asserting that the government cannot block rights to life, property, and liberty.
Step-by-step explanation:
The English philosopher who wrote the Second Treatise of Government is John Locke. In this work, Locke outlines his theory of natural law and natural rights, emphasizing that people have fundamental rights to life, liberty, and property.
He advocated for the concept of popular sovereignty, where governments should exist only with the consent of the people. Locke's idea that the government cannot take away an individual's right to life, property, and liberty was revolutionary at the time and later influenced the formation of democracies around the world, including the principles outlined in the United States Declaration of Independence.
Another historical figure, William Blackstone, wrote the Commentaries on the Laws of England, which is not directly mentioned in the provided information but is another significant work in the field of law. However, based on the resources provided, John Locke is the philosopher who supported the idea that natural law was given to humans by God, and he also maintained that the government cannot block a citizen's rights to life, property, and liberty.
