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

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.

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

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.

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

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.

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

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

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 the genus that gives the characters, and not the characters that make the genus.

If a tree dies, plant another in its place.

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

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

Nature does not proceed by leaps.

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.

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.

Basically, Herman van Rompuy wants the European Union to become a debt union, which may be acceptable to some of the southern countries who are effectively bust. To the northern countries, it is not.

No deals with the Tories; it’s war.

Before, Europe was about treaties, laws and our sovereign right to govern ourselves. Now, it’s about everyday lives.

What we are now doing with the victory, and I agree with you if you condemn that and I condemn whole-heartedly the trivial bullshit it is to go after a man who makes a scientific breakthrough and all that we as women — organized women — do is to fret about his shirt?

What I find daunting always is to stand on a stage and talk to people, whether they agree with me or not.

How we navigate between false agreement and polarization is the kind of mastery that collective wisdom represents.

When ordinary Soviet citizens are told that a vital trade agreement awarding their country most-favoured-nation status with the US is being blocked in Congress because Soviet Jews are demanding.

Our characterization of collective folly is that sound judgment is not feasible when there is forced or false agreement in groups.
