Meaning: The quote you've shared is from John Reagan, a prominent American politician who served as the Postmaster General of the Confederate States of America during the Civil War. The quote reflects Reagan's concerns about the potential impact of certain doctrines on the Federal Constitution, the character of the Federal Government, and the rights related to slavery.

Reagan's reference to "those doctrines" suggests that he is likely addressing a specific set of beliefs or principles that he believes could have far-reaching consequences. The first part of the quote, "The success of those doctrines would also subvert the Federal Constitution," indicates his fear that the implementation and acceptance of these doctrines could undermine the fundamental principles and structure of the Federal Constitution. This reflects a concern about the potential erosion of the rule of law and the balance of power between the federal government and the states.

Furthermore, Reagan's statement that the success of these doctrines would "change the character of the Federal Government" suggests that he believes they could alter the nature and functioning of the government itself. This could imply a shift in the balance of power, a change in the relationship between the branches of government, or a transformation in the government's role and responsibilities.

The final part of the quote, "and destroy our rights in respect to slavery," is particularly significant in the context of the time in which Reagan was speaking. As a politician from the Southern United States during the Civil War era, Reagan's concerns about the impact of doctrines on the rights related to slavery reflect the deeply entrenched and divisive nature of the issue at that time. The quote suggests that Reagan saw the potential success of these doctrines as a threat to the institution of slavery, which was a central point of contention leading up to the Civil War.

It's important to note that Reagan's perspective on the issue of slavery and the doctrines he references is a product of his historical context. The Civil War and the abolition of slavery represented a critical and deeply contentious period in American history, and Reagan's quote reflects the intense emotions and high stakes involved in the debates of that time.
