One ought to be ashamed to make use of the wonders of science embodied in a radio set, the while appreciating them as little as a cow appreciates the botanic marvels in the plants she munches.
— Albert Einstein

Literary criticism can be no more than a reasoned account of the feeling produced upon the critic by the book he is criticizing. Criticism can never be a science: it is, in the first place, much too personal, and in the second, it is concerned with values that science ignores. The touchstone is emotion, not reason. We judge a work of art by its effect on our sincere and vital emotion, and nothing else. All the critical twiddle-twaddle about style and form, all this pseudoscientific classifying and analyzing of books in an imitation-botanical fashion, is mere impertinence and mostly dull jargon.
D. H. Lawrence botanically quote

Live in each season as it passes; breathe the air, drink the drink, taste the fruit, and resign yourself to the influences of each. Let them be your only diet, drink, and botanical medicines.
— Henry David Thoreau

Nearly every season, I make the acquaintance of one or more new flowers. It takes years to exhaust the botanical treasures of any one considerable neighborhood, unless one makes a dead set at it, like an herbalist.
— John Burroughs

Bread without flesh is a good diet, as on many botanical excursions I have proved. Tea also may easily be ignored. Just bread and water and delightful toil is all I need - not unreasonably much, yet one ought to be trained and tempered to enjoy life in these brave wilds in full independence of any particular kind of nourishment.
— botanically quotation by John Muir
