It seems like you are referring to a specific excerpt from a letter written by Thomas Jefferson in response to the Supreme Court's decision in Marbury v. Madison (1803). This landmark case established the principle of judicial review in the United States, allowing the Supreme Court to invalidate laws that it finds to be unconstitutional.
In Jefferson's response, he expressed his concerns about the power of the judiciary and the implications of judicial review. Jefferson believed in a limited role for the judicial system, fearing that it might overreach its authority and infringe upon the powers of the legislative and executive branches.
If you need a more specific analysis of Jefferson's views or references from the letter, please provide additional details or context, and I would be happy to help!
