Think of instinct as an unscientific, unquantifiable tool that can be used along with more concrete evaluations to make a well-rounded decision.

Apostasy was the major justification for terminating internal opposition throughout the history of Islamic empires. That is why we have heard of whole tribes and groups being eradicated for apostasy. Muslim philosophers, mathematicians and scientists...

If scientific reasoning were limited to the logical processes of arithmetic, we should not get very far in our understanding of the physical world. One might as well attempt to grasp the game of poker...

My religious convictions and scientific views cannot at present be more specifically defined than as those of a believer in creative evolution. I desire that no public monument or work of art or inscription or...

Either god exists or it doesn’t exist. If a god does exist, it either interacts with the universe in some detectable way or it doesn’t. If it doesn’t, that god is indistinguishable from a non-existent...

There is in the chemist a form of thought by which all ideas become visible in the mind as strains of an imagined piece of music. This form of thought is developed in Faraday in...

I like the scientific spirit—the holding off, the being sure but not too sure, the willingness to surrender ideas when the evidence is against them: this is ultimately fine—it always keeps the way beyond open—always...

In 2003, I almost died of an intestinal blockage when I was on a mountain in Chile, filming a segment for ‘Scientific American Frontiers.’

Unfortunately, I have two facets to my makeup, and that is both scientific and artistic. By doing medicine, I was only answering one of those sides.

There is nothing distinctively scientific about the hypothetico-deductive process. It is not even distinctively intellectual. It is merely a scientific context for a much more general stratagem that underlies almost all regulative processes or processes...

Euclid’s Elements has been for nearly twenty-two centuries the encouragement and guide of that scientific thought which is one thing with the progress of man from a worse to a better state. The encouragement; for...

The most satisfactory definition of man from the scientific point of view is probably Man the Tool-maker.

When we consider the magnitude and extent of his discoveries and their influence on the progress of science and of industry, there is no honour too great to pay to the memory of Faraday, one...

ground rule” of science today which requires scientists to seek explanations in the world around us based upon what we can observe, test, replicate, and verify

On the ordinary view of each species having been independently created, we gain no scientific explanation.

There’s no such thing as an unbreakable scientific rule, because, sooner or later, they all seem to get broken. Or to change.

We can distinguish three groups of scientific men. In the first and very small group we have the men who discover fundamental relations. Among these are van’t Hoff, Arrhenius and Nernst. In the second group...

Very few, even among those who have taken the keenest interest in the progress of the revolution in natural knowledge set afoot by the publication of the ‘Origin of Species’; and who have watched, not...

Economics make homeopath and alternative healers look empirical and scientific.

Painting is so poetic, while sculpture is more logical and scientific and makes you worry about gravity.

Not only are there meaningless questions, but many of the problems with which the human intellect has tortured itself turn out to be only ‘pseudo problems,’ because they can be formulated only in terms of...

A scientific man ought to have no wishes, no affections, – a mere heart of stone.

Scientific experiments are expensive, and people are entitled to know about them if they want to. I think it is very difficult to convey ideas.
