That natural selection can produce changes within a type is disputed by no one, not even the staunchest creationist. But that it can transform one species into another — that, in fact, has never been...

In space you don’t stop.

La voluntad, el deseo de vivir, es tan fuerte en el animal como en el hombre. En el hombre es mayor la comprensión. A más comprender, corresponde menos desear. Esto es lógico, y además se...

Science and religion are not at odds. Science is simply too young to understand.

The only thing we can try to do is to influence the direction scientists are taking. Since we might soon be able to engineer our desires too, perhaps the real questions facing us is not...

Moreover, the sciences are monuments devoted to the public good; each citizen owes to them a tribute proportional to his talents. While the great men, carried to the summit of the edifice, draw and put...

The planet is finished with us, at this point –

I picture the vast realm of the sciences as an immense landscape scattered with patches of dark and light. The goal towards which we must work is either to extend the boundaries of the patches...

When they have discovered truth in nature they fling it into a book, where it is even worse hands.

Who that has ever visited the borders of this classic sea, has not felt at the first sight of its waters a glow of reverent rapture akin to devotion, and an instinctive sensation of thanksgiving...

I, on the other hand, am a finished product. I absorb electrical energy directly and utilize it with an almost one hundred percent efficiency. I am composed of strong metal, am continuously conscious, and can...

Names and attributes must be accommodated to the essence of things, and not the essence to the names, since things come first and names afterwards.

Journalism is not a precise science, it’s a crude art

The child is more individualised than the adult, the patient more than the healthy man, the madman and the delinquent more than the normal and the non-delinquent. In each case, it is towards the first...

The sciences have two extremities which meet. The first is the ignorance in which men find themselves at birth. The second is that attained by great souls. They have surveyed whatever man can know, find...

Asking where memory is “located” in the brain is like asking where running is located in the body. There are certainly parts of the body that are more important (the legs) or less important (the...

Nature seems to take advantage of the simple mathematical representations of the symmetry laws. When one pauses to consider the elegance and the beautiful perfection of the mathematical reasoning involved and contrast it with the...

Christians believe, as is reported in the New Testament scriptures, that Jesus of Nazareth healed 10 men with leprosy. It sounds like an astounding feat, but compare that to Jacinto Convit who saved thousands of...

Cuvier had even in his address & manner the character of a superior Man, much general power & eloquence in conversation & great variety of information on scientific as well as popular subjects. I should...

How did I discover saccharin? Well, it was partly by accident and partly by study. I had worked a long time on the compound radicals and substitution products of coal tar… One evening I was...

Experiment is the sole source of truth. It alone can teach us something new; it alone can give us certainty.

The earth is large and old enough to teach us modesty.

The element of chance in basic research is overrated. Chance is a lady who smiles only upon those few who know how to make her smile.

It is convenient for the old men to blame Eve. To insist we are damned because a country girl talked to the snake one afternoon long ago. Children must starve in Somalia for that, and...

If music serves to convey feelings through the interaction of physical gestures and sound, the musician needs his brain state to match the emotional state he is trying to express. Although the studies haven’t been...

Scientism and godism are superstitions, one blindly believes in what’s visible, the other blindly believes in what’s invisible.

Every instinct that is found in any man is in all men. The strength of the emotion may not be so overpowering, the barriers against possession not so insurmountable, the urge to accomplish the desire...

You can’t protect the world from itself, Gina. You can only give good men the tools necessary to do their jobs. We need to know what is possible.

Umut kendi içinde çelişkilidir (paradoksaldır). Ne edilgin bekleyiştir, ne de gerçekleşmesi olanaksız koşulların gerçekçi olmayan bir şekilde zorlanmasıdır. Atlama anı geldiğinde sıçrayacak olan çömelik bir kaplana benzer umut. Ne yorgun reformculuk umudun bir anlatımıdır ne...

And fragile is thy tenure of this worldStill haunted by the monstrous ghost of God.(“To Science”)

We are the intelligent elite among animal life on earth and whatever our mistakes, [Earth] needs us. This may seem an odd statement after all that I have said about the way 20th century humans...

… on these expanded membranes [butterfly wings] Nature writes, as on a tablet, the story of the modifications of species, so truly do all changes of the organisation register themselves thereon. Moreover, the same colour-patterns...

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.

…a wealth of information creates a poverty of attention…

It is a matter for considerable regret that Fermat, who cultivated the theory of numbers with so much success, did not leave us with the proofs of the theorems he discovered. In truth, Messrs Euler...

… respecto al origen del mundo, si es que lo tuvo, no nos queda más remedio que aceptar que nunca sabremos cómo ocurrió y que Dios es una explicación necia que no explica nada pues...

The theist and the scientist are rival interpreters of nature, the one retreats as the other advances.

These mysteries about how we evolved should not distract us from the indisputable fact that we did evolve.

The classification of facts, the recognition of their sequence and relative significance is the function of science, and the habit of forming a judgment upon these facts unbiased by personal feeling is characteristic of what...

It seemed to a number of philosophers of language, myself included, that we should attempt to achieve a unification of Chomsky’s syntax, with the results of the researches that were going on in semantics and...

A billion neutrinos go swimming in heavy water: one gets wet.

Puesto que el que contempla con sus ojos la belleza, no es ya tributario de la muerte, como dice Platen, sino de la Naturaleza, cuya belleza ha comprendido. Y si sus ojos sirven realmente para...

I don’t mind nothing happening in a book, but nothing happening in a phony way–characters saying things people never say, doing jobs that don’t fit, the whole works–is simply asking too much of a reader....

Science says: “We must live,” and seeks the means of prolonging, increasing, facilitating and amplifying life, of making it tolerable and acceptable, wisdom says: “We must die,” and seeks how to make us die well.

In describing a protein it is now common to distinguish the primary, secondary and tertiary structures. The primary structure is simply the order, or sequence, of the amino-acid residues along the polypeptide chains. This was...

Dr. Turing of Cambridge says that the soul is an illusion and that all that defines us as human beings can be reduced to a series of mechanical operations.

Muhammad introduced the concept of such Glorious and Omnipotent God in Whose eyes all worldly systems are pieces of straw. Islamic equality of mankind is no fiction as it is in Christianity. No human mind...

So far as we know, the tiny fragments of the universe embodied in man are the only centers of thought and responsibility in the visible world. If that be so, the appearance of the human...

There is no need to suffer silently and there is no shame in seeking help.
