Learning Pathway 2 has five activities. Each of the Journal activities is accompanied by an answer key. Once you have completed the journal entry, you can use the answer key to evaluate how successful you were in meeting the learning objectives. While the assessments are optional, and the grades will not be directly related to whether or not you receive credit for this course, completing them will help you gauge your progress and prepare for the TECEP\u00a9 exam.\n<\/p>\n

Journal Assignment 3<\/span><\/h2>\n

Identify the premises and conclusions in the following arguments:\n<\/p>\n

    \n
  1. If President Obama were wise, then he would withdraw his military forces from Iraq. He has withdrawn his forces from Iraq. Therefore, he must be wise.\n<\/li>\n
  2. Abortion is morally justified because a woman has a right to decide what happens to and in her body.\n<\/li>\n
  3. Since there are no mental diseases, there can be no treatments for them.\n<\/li>\n
  4. Prisons in South Africa are a failure. First, they do not rehabilitate anyone. Second, they don\u2019t so much punish as provide free room and board. Third, they bring criminals together, thereby allowing them to swop information and refine their felonious offences. Finally, those who have spent time in prison are far more likely to commit additional crimes than those who have never been in prison.\n<\/li>\n
  5. Capital punishment is morally wrong. It consists of killing human beings. The killing of human beings is morally wrong.\n<\/li>\n<\/ol>\n

    Journal Assignment 4<\/span><\/h2>\n

    Consider the following arguments and then analyze them by applying the steps to argument analysis:\n<\/p>\n

      \n
    1. The diseases that people develop and their chances of recovering from them are related to their personalities. Some types of personality are more likely to develop heart disease or back pain. And patients with cancer tend to respond better to treatment if they can maintain an optimistic, combative attitude. Sometimes they are taught to visualise their disease as an enemy and to imagine fighting it. This fosters states of mind that hinder the progress of the disease. So we need to influence the mind in order to influence the body: our minds are distinct factors that control our bodies.\n<\/li>\n
    2. Depression is a state of mind. But depression can often be relieved by antidepressant drugs. These drugs must affect our bodies, and in fact we know quite a lot about how they affect the brain. So changes in the brain can cause changes in the mind. So the mind is an aspect of the brain.\n<\/li>\n
    3. Noise is an environmental pollution which upsets people, causes tempers to fray and builds up tension between neighbours. People tolerate a great deal of unnecessary noise even though it often drives them to distraction. Local authority noise patrols can obtain warrants to enter premises where noise and alarms are disturbing the neighbourhood. They can oppose the renewal of licences for noisy pubs. They can apply to the courts for fines of up to $4,000 for persistent noise offenders.\n<\/li>\n
    4. The fact is indisputable that, taking the average, say, of a hundred brains, the man has five or six ounces more brain than the woman. Some women will, of course, be found to have much larger brains than some men; but whenever the comparison embraces a sufficient number to yield a fair average, the superiority is invariably on the side of the man. And it is worthy of special remark that it is in the cerebrum, or brain proper, that these differences are very trifling. Now, when we reflect that the cerebrum is generally supposed to be the exclusive organ of the intellectual, volitional, and emotive faculties, and that it forms about nine-tenths of the whole mass usually designated as \u201cthe brain\u201d, or more correctly as \u201cthe encephalon\u201d, this marked superiority in the male cerebrum seems to lend scientific authority to the general verdict regarding the intellectual inferiority of women.\n<\/li>\n<\/ol>\n
