Hope not for impossibilities.
Methinks there be not impossibilities enough in religion for an active faith.
Do not mathematics and all sciences seem full of contradictions and impossibilities to the ignorant, which are all resolved and cleared to those that understand them?Richard Baxter
There are necessities and impossibilities in reality which do not obtain in fiction , any more than the law of gravity to which we are subject controls what is represented in a picture. ... It is the same with pure good; for a necessity as strong as gravity condemns man to evil and forbids him any good, or only within the narrowest limits and laboriously obtained and soiled and adulterated with evil. ... The simplicity which makes the fictional good something insipid and unable to hold the attention becomes, in the real good, an unfathomable marvel.Simone Weil
The best paradoxes raise questions about what kinds of contradictions can occur what species of impossibilities are possible.william poundstone
The recognition of certain basic impossibilities has laid the foundations of some major principles of physics and chemistry; similarly, recognition of the impossibility of understanding living things in terms of physics and chemistry, far from setting limits to our understanding of life, will guide it in the right direction. And even if the demonstration of this impossibility should prove of no great advantage in the pursuit of discovery, such a demonstration would help to draw a truer image of life and man than that given us by the present basic concepts of biology.
Probable impossibilities have to be preferred to improbable possibilities.
