Basic logic help.was my teacher wrong?

Topic: Definition of a research statement
July 16, 2019 / By Dorine
Question: The statement was "If an argument is cogent, then it is also valid" I said false, but the answer is true and I'm wondering why? Cogent makes it's a true strong INDUCTIVE argument and inductive arguments are inferred, but to be valid, it MUST logically follow with certainty. What am I missing? Could she be wrong when she marked the test?

The first answer would have been mine, but I kept looking because I like to research--and I found something surprising: Cogency • Some invalid arguments are better than others (from a logical point of view). Some are cogent, while others are not. • In fact, cogency comes in degrees. Here is an example: 1. Boris is a student at State U. 2. Almost all students at State U. voted. --------------------------------------... 3. Boris voted. • This argument is invalid, because it is possible for its conclusion to be false, even given the truth of its premises. • But, this argument is cogent, since its conclusion is probable, given the truth of all of its premises. That leads to our definition. Cogency • D3.2a: An argument is cogent if it is not valid, but its conclusion is probable, given the truth of its premises. • As a result of this definition, cogency comes in degrees. The more probable the conclusion is (given the truth of all the premises!), the stronger the cogency of the argument is. Form: 1. n% of As are Bs. 2. x is an A. ------------------------ 3. x is a B. • If n > 50, then the argument is cogent (if n =100, the argument is valid). If n ≤ 50, the argument is not (even) cogent. see #38 and #39 http://fitelson.org/101/notes_11-2x2.pdf Wow! In everyday language 'cogent' means 'sounds very likely'. That is what this link says, but gives the probability 'greater' or 'lesser' cogency. So if it is 100% cogent, it is also valid, and may be sound, but not necessarily so. 'Certainty' (as in 100%) has nothing to do with it.

amazing... *clap* never thought of it that way. u die a hero... that automatically gets u through the gates I would say... or God might be an *** and justify it as suicide... whatever. brilliant plan though. on a side note... dont kill unborn children! just because God doens't exist doesn't make it right to kill babies. on another note... Earth is so overpopulated... do what you will... EDIT: ahh those idiots up there didn't read a single thing you wrote. 1. he knows he's sinning, that's why he is sacrificing himself to go through with this plan. 2. if you didn't want to read his "important, profound" original thought, why did you click on this? were you looking for thoughts of others that agree to you? 3. keep his morality off you? the true test of how good your current morality is, is to see if it repels others.

Abortion is murder of innocent blood. If you can play you can take responsibility for your action. Abortion is the slaughter of a soul God wanted to be born into the world. St.Gianna sacrificed her own life for that of her unborn child and was recently canonized a Saint for choosing the life of her baby over her own. Being a women is a glorious gift because our bodies cooperate with the divine will of God to send souls into the world and because of this all married women have a duty to put the lives of their unborn children over that of their own. As a mother I would give my life for my baby even if she wasn't born yet. In today's society we see young unmarried women having meaningless sex for the "fun" of it. Sex in and of itself is a selfless act of love that should only happen between a married couple and it should always be opened to conception of life. Unfortunately so many women have been brainwashed by TV and popular music to think sex is only for fun. But if more women were to treat their bodies as temples of the Holy Spirit there would be less disease, no abortion and honestly a greater respect not only for the lives of the unborn but of our elderly and those sick and/or dying. If we buy into the culture of death then being promiscuous without consequence makes sense, just go get the procedure done no problem. What many don't understand is the huge link between abortion and breast cancer and one sin can cause not only mental issues for the woman but also physical issues such as not ever being able to conceive again or getting a disease like breast cancer. It is truly sad that so many believe that babies in the womb are nothing but a pile of matter, when in all actuality if you want your baby then you call it a baby from the moment you find out you are pregnant, and when you don't want the baby it is no longer a baby but a fetus. Go figure. Life is NOT the choice of a woman but the responsibility of a MOTHER. Abortion in all cases and scenarios is wrong no matter the circumstance. Love and God bless you, Kate

first of all it's altruism not alturism. your premises and logic are flawed unfortunately. "therefore, as an atheist, my act of encouraging if not carrying out abortions with willing females is an act of alturism." should we accept this, then it is also logical to kill babies and little kids for they are innocent too and by killing them, we are "saving" them and ushering them to heaven. which is reminiscent of Jonestown in the sense that Jim Jones supposedly "saved" his followers from this earth. who says that the fetus cannot feel pain? the moment the sperm unites with the egg cell, life begins. how is it then that it's heartbeat can be detected even at the very earliest stage of development? just because it cannot speak nor defend itself doesn't mean it cannot feel. christians are against abortion because it is murder. who are we to end another's life? and decide for them that "it's better to die so they can go to heaven"? what if it wants to live and be an atheist just like you? you grew up to be an unbeliever. would you want someone killing you in the womb so you can go to heaven? eventhough you don't believe in it? no human being has the right to decide for you nor for me. you're "logic" cannot stand in court unfortunately.

"A cogent argument is a strong argument in which all the premises are actually true in our world." Ultimately, you must refer to how your course and your professor defined a cogent argument, especially since your own description lacks clarity.

Thank god Mccain didnt win. We woulda been way up the **** creek. Republicans believe in tax cuts for the rich and struggles for the poor. I dont understand why half the population is republican. they only help the rich, big corp business, and less that 5 percent of the population is rich. Obama did the best he could. He had great ideas, but the republicans kept voting against all his bills. its a real shame. plus its hard to recover in just 4 years, the economy just went to **** after bush. september 11th happened, katrina happened, the war happened, the tax cuts happened, everything. taxes are important. thats how we pay for our ****. clinton had our economy thriving, we had no debt. bush kept borrowing money from china and **** to support that unnecessary war and tax cuts. romney is a tard. he keeps talking about what obama failed to do. but he never backs it up. never once have i heard a single solution or plan out of his mouth. he doesnt even acknowledge the fact that obama tried to change things but kept getting out voted by the republicans. he doesnt mention the jobs he saved by bailing out those car companies. i mean romney used his horseriding as a business to get out of paying more taxes. really? wow. hes a shmuck

after reading the liberal posts above, it further reinforces my belief that liberals dont take responsibility for their actions, just blame others the blame Bush game has long been played out... from reading the posts, Clinton and Obama did and have done no wrong, which they have, and Bush has done no right, which is false... one of the reasons Clinton left a surplus was because he gutted the military... many terrorist attacks and incidents happened on his watch, but u wont hear liberals / Democrats mention any of it... 9/11 was planned under his watch, but nothing was done about it... fast forward to Obama... he is trying the old tried and false method of spending America into prosperity which will fail... and yet the liberal / Democrat worshippers of his gladly cheer his tax increases - Obamacare comes to mind - and say its the Republicans fault the country is going down the drain we are no better now than we were 4 years ago, unemployment is actually worse now, we are in higher debt than at any other point in American history, yet a sizable percentage of the population votes Democrat which is the party of higher taxes and nanny-state government... many countries around the world do not take us seriously, what with Obama being a laughingstock and all... and the Obama worshippers stubbornly insist he has all the answers and can do no wrong... its pretty scary actually to see the mentality of the American electorate that voted him into office in 2008
