Due to some dim but irresistible notion of the way things are, it is simply not possible, out of order, not apprpriate to the situation at hand, if, within the circle of those who are experienced and advanced in years, the young person declaims ethical generalities. Young people will again and again find themselves in a situation that is so irritating, astounding, and incomprehensible to them that their word falls on deaf ears, while the word of an older person is heard and has weight even though its content is no different at all. It will be a sign of maturity or immaturity whether this experience leads them to understand that what is at stake here is not the stubborn self-satisfaction of old age, or the anxious effort to keep youth in their place, but the pereservation or violation of an essential ethical law. Ethical discourse needs authorization, which youth are simply not able to bestow upon themselves, even if they speak out of the purest pathos of their ethical conviction. Ethical discourse does not merely depend on the correct content of what is said, but also on the speaker being authorized to say it. Its validity depends not only on what is said, but also on who says it.

One may characterize physics as the doctrine of the repeatable, be it a succession in time or the co-existence in space. The validity of physical theorems is founded on this repeatability.

Logic, it is often said, is the study of valid arguments. It is a systematic attempt to distinguish valid arguments from invalid arguments.

Abraham Lincoln quoted the Scriptures in an 1858 speech to the Illinois Republican Convention. He said, “ A house divided against itself cannot stand.” That, I fear, is where diversity leads. If by that term we refer to love and tolerance for peoples who are different from one another, it has great validity for us. But if by diversity we mean that all of us have been given reason to resent one another. Having no common values, heritage, commitment, or hope, then we are a nation in serious trouble.

Don't tell a lie to be loved, speak the truth to be hated.

The simple truth is that the only real 'ex-gay' person is a dead gay person - and even then I am not too sure about the validity of that statement.

Whatever you tell; lie or truth, can both destroy or save you.

When you raise the most valid of points, you will be grazed by the most hollow of souls, and the most vacant of personages.

A goal lacking a sense of ethics is a goal that lacks any sense.

The motive behind criticism often determines its validity. Those who care criticize where necessary. Those who envy criticize the moment they think that they have found a weak spot.
