In mathematical logic, a logical system has the soundness property if and only if its inference rules prove only formulas that are valid with respect to its semantics. In most cases, this comes down to its rules having the property of preserving truth, but this is not the case in general.
An argument is sound if and only if
1. The argument is valid, and 2. All of its premises are true.
For instance,
The argument is valid (because the conclusion is true based on the premises, that is, that the conclusion follows the premises) and since the premises are in fact true, the argument is sound.
The following argument is valid but not sound:
Since the first premise is actually false, the argument, though valid, is not sound.
Soundness is among the most fundamental properties of mathematical logic. The soundness property provides the initial reason for counting a logical system as desirable. The completeness property means that every validity (truth) is provable. Together they imply that all and only validities are provable.
In this video, Aaron Ancell (Duke University) discusses the philosophical concept of soundness. After reviewing validity, he defines soundness: an argument is sound when it is valid and has all true premises. He reviews a few examples of sound and unsound arguments, and he encourages you to develop sound arguments on your own. Help us caption & translate this video! http://amara.org/v/Gqe5/

철도 파업 지속, 열차 운영 평소 94.2% As of Sunday, the nation's unionized rail workers are on strike for a 13th day. According to Korea Railroad or KORAIL, trains are running at 94-point-2 percent the normal level. High-speed KTX and commuter trains operating at full capacity... but the number of freight trains running will be drastically reduced on Monday. The 85 percent operational level will not be maintained come Monday for a number of reasons. For one, significantly fewer trains are needed for freight services over the weekend. And Korean Cargo Transport Workers' Union will begin their demonstations at the start of the week. They're demanding the government scrap its reform plan which would result in more trucks for big companies, dealing a blow to small cargo truck operators. Their first walkout...
Professor Thorsby explains the difference between valid and invalid arguments.

Just as a torn fingernail will not heal, but has to grow back, also is the hoof of the horse, when the laminea is stretched. Sometimes horses with lamintis or founder develope huge gaps between the wall and the foot, that become filled with dead necrotic laminea tissue. This has to be removed for the hoof wall to ever grow back correctly. This laminar wedge as it's called is also what causes the most pain in laminitis. Learn how to relieve it and release the pressure from the horses foot and the horse will be more comfortable.

The Soundness Among The Nation Of YisraYah
'The Soundness of a Mariology Cured of its Maximalist canker': Yves Conger on Mary in the Mystery of Christ and His Church - presented by Professor Christopher Ruddy, Associate Professor of Theology, Catholic University of America
Oh Danny boy, the pipes, the pipes are calling
From glen to glen, and down the mountain side
The summer's gone, and all the flowers are dying
'Tis you, 'tis you must go and I must bide.
But come ye back when summer's in the meadow
Or when the valley's hushed and white with snow
'Tis I'll be here in sunshine or in shadow
Oh Danny boy, oh Danny boy, I love you so.
And if you come, when all the flowers are dying
And I am dead, as dead I well may be
You'll come and find the place where I am lying
And kneel and say an "Ave" there for me.
And I shall hear, tho' soft you tread above me
And all my dreams will warm and sweeter be
If you'll not fail to tell me that you love me
I'll simply sleep in peace until you come to me.
