Bioethics Final Review

may be invalid; sound or unsound
technically always invalid
uses generalizations and inferences
two or more persons are required to drive in the diamond lane. you don't have two or more persons. therefore you may not drive in the diamond lane
involves going from specific cases to a broad or general conclusion
the conclusion is not guaranteed, one can argue against it by finding counterexamples
the conclusion is guaranteed...the premises entail the conclusion so it has to be true

a branch of philosophy that studies theories and arguments and why the actions are right or wrong or the state of affairs are good or bad
the set of premises that help convince us that a conclusion is true
an attempt to identity the common thread or general rule, that explains why an action is right or wrong
actions are judges right or wrong solely by their consequences
divine command theory

morals are internal
no, some laws are legal but not moral. some laws are not moral, but legal

are morality and religion the same thing?
3, 4, 2, 1
put the following statements in a natural flow. if we can prevent something very bad from happening by doing x, and if we can do x without sacrificing something of comparable moral worth, then we have a moral duty to do x. therefore, we have a moral duty to send substantial amounts of money for famine relief. by sending substantial amounts of money for famine relief, we can prevent death by starvation without sacrificing anything of comparable moral worth. death by starvation is a very bad thing

underline premise and circle conclusion: genetic engineering is when you manipulate the dna of an organism. when this is done, it is possible that the dna may be damaged and it could cause the organism great harm; therefore, we should take precaution whenever doing genetic engineering
underline premise and circle conclusion: transgenic crops are crops that have been genetically engineered. transgenic crops could possibly cause harm to the environment because they are "unnatural: and could end up depleting our "natural" crops.
underline premise and circle conclusion:if we waste paper, we are wasting trees. trees are a valuable resource; therefore, we should not waste paper.
underline premise and circle conclusion: genetic screening is a way to identify is a child has a genetic disease before they are born. being able to tell if a child has a disease will allow the parents to best prepare for their new child. therefore, genetic screening is a beneficial technology.
incorrect, use natural order (therefore, cloning is morally wrong)
correct or incorrect? cloning reduces individuality. cloning is the process where an organisms' dna can be replicates and turned into a new organism. therefore, cloning is morally wrong. reducing individuality is morally wrong.
incorrect, using a premise that isn't general (feral)
correct or incorrect? using snare traps to kill the feral pigs will hurt them. so it is wrong to use snare traps to kill feral pigs.
incorrect, use consistent terms (transgenics)
correct or incorrect? genetic engineering is the process in which an organisms' genetic material is manipulated in some way. gene manipulation can be a very dangerous process. when we transfer genes between species, we may cause damage that cannot be repaired. transgenics is therefore not a good thing.
incorrect use reliable premise (first sentence)
correct or incorrect? we will never have too our our math skills in the real world, not even simple addition. therefore, i will not even attempt to learn math...its pointless.
invalid, unsound
some cats are mammals, all mammals are warm-blooded; therefore, all cats are warm-blooded
valid, unsound

valid, sound
all cats are mammals, all mammals are warm-blooded;therefore, cats are warm-blooded
