Carl Linnaeus quotes:

  • This drink has a magical power. It strengthens the weak, and revives those who have fainted. Those tired after work and physical activity can return their life forces by this drink much sooner than by nourishment. ... It works as a diuretic, an appetizer, an antitoxin.

  • Natural bodies are divided into three kingdomes of nature: viz. the mineral, vegetable, and animal kingdoms. Minerals grow, Plants grow and live, Animals grow, live, and have feeling.

  • Linnea.... A plant of Lapland, lowly, insignificant, disregarded, flowering but for a brief space - from Linnaeus who resembles it.

  • Nomenclature, the other foundation of botany, should provide the names as soon as the classification is made... If the names are unknown knowledge of the things also perishes... For a single genus, a single name.

  • If a tree dies, plant another in its place.

  • Botany is based on fixed genera.

  • There are some viviparous flies, which bring forth 2,000 young. These in a little time would fill the air, and like clouds intercept the rays of the sun, unless they were devoured by birds, spiders, and many other animals.

  • A practical botanist will distinguish at the first glance the plant of the different quarters of the globe and yet will be at a loss to tell by what marks he detects them.

  • The species and the genus are always the work of nature [i.e. specially created]; the variety mostly that of circumstance; the class and the order are the work of nature and art.

  • No one has been a greater botanist or zoologist. No one has written more books, more correctly, more methodically, from personal experience. No one has more completely changed a whole science and started a new epoch.

  • It is not God, but people themselves who shorten their lives by not keeping physically fit.

  • I demand of you, and of the whole world, that you show me a generic character... by which to distinguish between Man and Ape. I myself most assuredly know of none.

  • A professor can never better distinguish himself in his work than by encouraging a clever pupil, for the true discovers are among them, as comets amongst the stars.

  • Stones grow, plants grow, and live, animals grow live and feel.

  • Nature does not proceed by leaps.

  • In natural science the principles of truth ought to be confirmed by observation.

  • As one sits here in summertime and listens to the cuckoo and all the other bird songs, the crackling and buzzing of insects, as one gazes at the shining colors of flowers, doth one become dumbstruck before the Kingdom of the Creator.

  • Blessed be the Lord for the beauty of summer and spring, for the air, the water, the verdure, and the song of birds.

  • The first step in wisdom is to know the things themselves; this notion consists in having a true idea of the objects; objects are distinguished and known by classifying them methodically and giving them appropriate names. Therefore, classification and name-giving will be the foundation of our science.

  • If you do not know the names of things, the knowledge of them is lost, too.

  • The plant kingdom covers the entire earth, offering our senses great pleasure and the delights of summer.

  • Yet man does recognise himself [as an animal]. But I ask you and the whole world for a generic differentia between man and ape which conforms to the principles of natural history, I certainly know of none... If I were to call man ape or vice versa, I should bring down all the theologians on my head. But perhaps I should still do it according to the rules of science.

  • Of what use are the great number of petrifactions, of different species, shape and form which are dug up by naturalists? Perhaps the collection of such specimens is sheer vanity and inquisitiveness. I do not presume to say; but we find in our mountains the rarest animals, shells, mussels, and corals embalmed in stone, as it were, living specimens of which are now being sought in vain throughout Europe. These stones alone whisper in the midst of general silence.

  • It is the genus that gives the characters, and not the characters that make the genus.

  • To live by medicine is to live horribly.

  • We admit as many genera as there are different groups of natural species of which the fructification has the same structure.

  • Nature's economy shall be the base for our own, for it is immutable, but ours is secondary. An economist without knowledge of nature is therefore like a physicist without knowledge of mathematics.

  • A herbarium is better than any illustration; every botanist should make one.

  • When all the thoughts are concerning one thing and the person loses interest in other things, the melancholy begins.

  • The names of the plants ought to be stable [certa], consequently they should be given to stable genera.

  • Fragments of the natural method must be sought with the greatest care. This is the first and last desideratum among botanists. Nature makes no jumps. [Natura non facit saltus] All taxa show relationships on all sides like the countries on a map of the world.

  • There is no generation from an egg in the Mineral Kingdom. Hence no vascular circulation of the humours as in the remaining Natural Kingdoms.

  • There are as many species as the infinite being created diverse forms in the beginning, which, following the laws of generation, produced many others, but always similar to them: therefore there are as many species as we have different structures before us today.

  • All the species recognized by Botanists came forth from the Almighty Creator's hand, and the number of these is now and always will be exactly the same, while every day new and different florists' species arise from the true species so-called by Botanists, and when they have arisen they finally revert to the original forms. Accordingly to the former have been assigned by Nature fixed limits, beyond which they cannot go: while the latter display without end the infinite sport of Nature.
