A. How have laws, policies, and systems developed to enforce the enslavement of black Americans before the Civil War influenced laws, policies, and systems in years since?

As the Civil War came to a close, southern states began to pass a series of discriminatory state laws collectively known as black codes. While the laws varied in both content and severity from state to state—some laws actually granted freed people the right to marry or testify in court— these codes were designed to maintain the social and economic structure of racial slavery in the absence of the “peculiar institution.” The laws codified white supremacy by restricting the civic participation of freed people; the codes deprived them of the right to vote, the right to serve on juries, the right to own or carry weapons, and, in some cases, even the right to rent or lease land.

Slavery had been a pillar of economic stability in the region before the war; now, black codes ensured the same stability by recreating the antebellum economic structure under the façade of a free-labor system. Adhering to new “apprenticeship” laws determined within the black codes, judges bound many young African American orphans to white plantation owners who would then force them to work. Adult freedmen were forced to sign contracts with their employers—who were oftentimes their previous owners. These contracts prevented African Americans from working for more than one employer, and therefore, from positively influencing the very low wages or poor working conditions they received.

Any former slaves that attempted to violate or evade these contracts were fined, beaten, or arrested for vagrancy. Upon arrest, many “free” African Americans were made to work for no wages, essentially being reduced to the very definition of a slave. Although slavery had been outlawed by the Thirteenth Amendment, it effectively continued in many southern states..!!

the support that the author, uses in the article facing our fears is a): a definition of the part of the brain called the amygdala.

he takes neuroscientist joseph ledoux's words by telling that by falling to distinguish between evolutionary old systems located in the amygdala and newer systems, centered in the prefrontal cortex, doctors have conflated non conscious threat circuits in the brain with circuits that underlie the conscious experience of fear. that, the author says, "leads ledoux to the jarring conclusion that the amygdala, a decades-old centerpiece of the brain's fear circuit, does not underlie the conscious feeling of fear".

despite this, the author points out in the article that that is a controversial notion and that evidence, in animal and humans, supports the idea that core emotions can exist outside of conscious awareness.
