David Frost: If you haven't got nuclear weapons, the choice in that situation would be to subject your forces to an unfair battle. Neil Kinnock: Yes, what you're suggesting is that the alternatives are between the gesture, the threat, or the use of nuclear weapons, and surrender. In these circumstances the choice is posed, and this is a classical choice, between exterminating everything you stand for and the flower of your youth, or using all the resources you have to make any occupation totally untenable.
If in the vast majority of possible cases in all of ordinary occurrence the law is in no degree inconsistent or unreasonable, construed according to its plain words, it seems to me to be an untenable proposition, and unsupported by authority, to say that the construction may be varied in every case because there is one possible, but highly improbable one, in which the law would operate with great severity, and against our own notions of justice.
The belief that God will do everything for man is as untenable as the belief that man can do everything for himself. It, too, is based on a lack of faith. We must learn that to trust God with the expectation that he will do everything while we do nothing, is not faith, but superstition.
Each new ontological theory, propounded in lieu of previous ones shown to be untenable, has been followed by a new criticism leading to a new scepticism. All possible conceptions have been one by one tried and found wanting; and so the entire field of speculation has been gradually exhausted without positive result: the only result reached being the negative one above stated, that the reality existing behind all appearances is, and must ever be, unknown.Herbert Spencer
The above observation makes the hypothesis advanced by those who see Muhammad as the author of the Qur'an untenable. How could a man, from being illiterate, become the most important author, in terms of literary merits, in the whole of Arabic literature? How could he then pronounce truths of a scientific nature that no other human being could possibly have developed at that time, and all this without once making the slightest error in his pronouncement on the subject?"
