Here is the ready-to-answer question of Christian theology

January 27: Rigby, Speaking of God (chapter three on Incarnation)

Question: Drawing on Rigby's observations on pp. 86-90 (on Chalcedon), what difference does Jesus being fully divine and fully human make to how you live your everyday life as a person of faith? If you don't identify as Christian, how do you think the identify of Jesus should influence Christian choices?

      In her book Living by Fiction, Annie Dillard points out, along these lines, that most of what we have to say to one another is about "artifacts"-that is, specific things that have already been made by human beings that can be created, managed, examined, known, and mastered. 86  Dillard seems to include, in her understanding of artifacts, not only physical objects we make and use, or make and admire. She includes, also, the systems we develop that frame what is beyond our scope-perhaps the periodic table, the color wheel, or, even, a birdwatchers' guide. What is lacking in our world and our lives is not intriguing discussions of artifacts. What is lacking, she says, are those who are courageous enough to say something immediate about existence itself. "Who will interpret the raw universe?" she asks. "We have a shortage of metaphysicians." 87   This is a problem, Dillard thinks, because "if we confine our interpretive investigations to strictly bounded aspects of culture ... we miss learning what we most want to know."88

Support your answer with your current understanding of gender differences in brain regions of bird.

In your own words, how is the brain involved (i.e., what brain structures) in producing a sentence? How is it involved in understanding a sentence? Does thinking of the brain as a network simplify your understanding of language/speech, or do you find it to be more complex?

After you have digested the details of brain organization that underlie language function, it’s a good time to review. In your own words, how is the brain involved (i.e., what brain structures) in producing a sentence? How is it involved in understanding a sentence? Does thinking of the brain as a network simplify your understanding of language/speech, or do you find it to be more complex?

An understanding of the brain is basic to biopsychology and all of neuroscience. The following question about the brain has three parts: (1) Why do we study the brain? (2) What does the brain do. i.e., what is the function of the brain? (3) How do we study the brain?

This question has three parts: (1) Identify two contributors to the development of biopsychology-neuroscience. (2) Describe the ideas and/or research that the person is famous for. (3) Discuss the reasons their contributions are important to the field of contemporary biopsychology.
