It happens as one sees in cages: the birds who are outside despair of ever getting in, and those within are equally desirous of getting out – Michel de Montaigne
The beginning, middle, and end of the birth, growth, and perfection of whatever we behold is from contraries, by contraries, and to contraries; and whatever contrariety is, there is action and reaction, there is motion, diversity, multitude, and order, there are degrees, succession and vicissitude. – Giordano Bruno
