As far as I know, there is no proof whatever of the existence of an objective reality apart from our senses, and I do not see why we should accept the outside world as such solely by virtue of our senses.
M. C. EscherI try in my prints to testify that we live in a beautiful and orderly world, and not in a formless chaos, as it sometimes seems.
M. C. EscherAlthough I am even now still a layman in the area of mathematics, and although I lack theoretical knowledge, the mathematicians, and in particular the crystallographers, have had considerable influence on my work of the last twenty years. The laws of the phenomena around us--order, regularity, cyclical repetition, and renewals--have assumed greater and greater importance for me. The awareness of their presence gives me peace and provides me with support.

M. C. EscherOnly those who attempt the absurd will achieve the impossible. I think it's in my basement... let me go upstairs and check.
M. C. EscherThere is something breathtaking about the basic laws of crystals. They are in no sense a discovery of the human mind; they just "are" - they exist quite independently of us. The most that man can do is become aware, in a moment of clarity, that they are there, and take cognizance of them.
