Don't you see that the appalling history of sectarianism, persecution, heresy hunting, shows you that this way of thinking about the world is intrinsically unsound?
Some of the sharpest men in argument are notoriously unsound in judgment.Oliver Wendell Holmes
"The unsound convert takes Christ by halves. He is all for the salvation of Christ, but is not for sanctification. He is for the privileges, but does not appropriate the person of Christ."joseph alleine
I have read their platform, and though I think there are some unsound places in it, I can stand upon it pretty well. But I see nothing in it both new and valuable. "What is valuable is not new, and what is new is not valuable."Daniel Webster
The errors which arise from the absence of facts are far more numerous and more durable than those which result from unsound reasoning respecting true data.Charles Babbage
Our industrial design is very bad still a great deal of it though infinitely better than it was thirty years ago. So a great deal of our teaching of design may be, I fear is, unsound; but all the sound teaching we have is through such schools as this, and even in our errors there is, let us hope, instruction.
At first I hoped that such a technically unsound project would collapse but I soon realized it was doomed to success. Almost anything in software can be implemented, sold, and even used given enough determination. There is nothing a mere scientist can say that will stand against the flood of a hundred million dollars.
The supposed great library at Alexandria was destroyed by the men of Mohammed for the, to them, satisfactory reason that if the books in it agreed with the Koran they were unnecessary, and if they did not agree with it they were unsound. Will ever some devoted advocate or some legions of such devotees of the real law the red-eyed kind, if you please arise and settle this question by a conflagration?
The appearance... of limestone beds in the early part of the stratified series, may be presumed to be connected with the fact of the commencement of organic life upon our planet, and, indeed, a consequent and a symptom of it. ...My hypothesis may indeed be unsound; but, whether or not, it is clear, taking organic remains as upon the whole a faithful chronicle, that the deposition of these limestone beds was coeval with the existence of the earliest, or all but the earliest, living creatures upon earth.Robert Chambers
