More quotes by Humphry Davy

Image
Nature is beautiful, and you are in her bosom. That voice of comfort which speaks in the breezes of morning, may visit your mind, that the delightful influences which the green leaves, the blue sky, the moonbeams and clouds of the evening diffuse over the universe, may in their powers of soul-healing, visit your day visions, is my desire and hope.
Humphry Davy
Image
Language is not only the vehicle of thought, it is a great and efficient instrument in thinking.
Humphry Davy
Image
Gay-Lussac was quick, lively, ingenious and profound, with great activity of mind and great facility of manipulation. I should place him at the head of all the living chemists in France.
Humphry Davy
Image
It must always be borne in mind that the assumption of woman's social superiority lies at the root of these rules of conduct.
Humphry Davy
Image
There may be beings, thinking beings, near or surrounding us, which we do not perceive, which we cannot imagine. We know very little but, in my opinion, we know enough to hope for the immortality, the individual immortality, of the better part of man.
Humphry Davy
Image
Fortunately science, like that nature to which it belongs, is neither limited by time nor by space. It belongs to the world, and is of no country and no age. The more we know, the more we feel our ignorance the more we feel how much remains unknown.
Humphry Davy
Image
The most important of my discoveries have been suggested to me by failures.
Humphry Davy
Image
Oh, most magnificent and noble Nature! Have I not worshipped thee with such a love As never mortal man before displayed? Adored thee in thy majesty of visible creation, And searched into thy hidden and mysterious ways As Poet, as Philosopher, as Sage?

The art galleries of Paris contain the finest collection of frames I ever saw.

Image
In the present state of our knowledge, it would be useless to attempt to speculate on the remote cause of the electrical energy... its relation to chemical affinity is, however, sufficiently evident. May it not be identical with it, and an essential property of matter?
Humphry Davy
Image
Consistency in opinion is the slow poison of intellectual life, the destroyer of its vividness and energy.
Humphry Davy
Image
The well-mannered man never puts out his hand in greeting until a lady extends hers. This is a test of good breeding that is constantly applied. ... The first move in the direction of cordiality must come from the lady, the whole code of behaviour being based on the assumption that she is the social superior.
Humphry Davy
Image
By science calmed, over the peaceful soul, Bright with eternal Wisdom's lucid ray, Peace, meek of eye, extends her soft control, And drives the puny Passions far away.
Humphry Davy
Image
The three states of the caterpillar, larva, and butterfly have, since the time of the Greek poets, been applied to typify the human being,--its terrestrial form, apparent death, and ultimate celestial destination.
Humphry Davy
Image
Nothing tends so much to the advancement of knowledge as the application of a new instrument.
Humphry Davy
Image
When two elements combine and form more than one compound, the masses of one element that react with a fixed mass of the other are in the ratio of small whole numbers.
Humphry Davy
Image
The wealth and prosperity of the country are only the comeliness of the body, the fullness of the flesh and fat but the spirit is independent of them it requires only muscle, bone and nerve for the true exercise of its functions. We cannot lose our liberty, because we cannot cease to think.
Humphry Davy
Image
Experimental science hardly ever affords us more than approximations to the truth and whenever many agents are concerned we are in great danger of being mistaken.
Humphry Davy
Image
Nothing is so dangerous to the progress of the human mind than to assume that our views of science are ultimate, that there are no mysteries in nature, that our triumphs are complete and that there are no new worlds to conquer.
Humphry Davy
Image
I envy no quality of the mind or intellect in others not genius, power, wit, nor fancy but, if I could choose what would be most delightful, and, I believe, most useful to me, I should prefer a firm religious belief to every other blessing.
