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

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

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.

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.

Freedom will destroy itself if it is not exercised within some sort of moral framework, somebody of shared beliefs, some spiritual heritage transmitted through the Church, the family, and the school.

Voting is the most powerful right of every citizen and it is our duty to exercise our vote.

My whole life has been a hallow waste, a futile exercise, for no one at death can take anything with them!

I’ve learned to not beat myself up about needing relaxation. To not stress about exercise and doing stuff. It’s important to counterbalance yourself.

Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind.

The fact that I can plant a seed and it becomes a flower, share a bit of knowledge and it becomes another’s, smile at someone and receive a smile in return, are to me continual spiritual exercises.

Exercising the imagination, experimenting with talents, being creative; these things, to me, are truly the windows to your soul.

Being entirely honest with oneself is a good exercise.
