Dear Colleagues,

The Einstein quote that Eva is probably seeking is this:

"Imagination is more important than knowledge. For knowledge is
limited, whereas imagination embraces the entire world, stimulating
progress, giving birth to evolution."

I have seen this quoted often. I have not yet traced it to Einstein's
own writings. If anyone has the actual source for this, I would be
delighted to have the reference.

In the meantime, I'll take a moment to offer a few thoughts on things
I know for a fact that Einstein DID say and write, and I'll provide
the sources for anyone who wishes to loom further.

Einstein was famous for his belief in the imagination. This fact
captivates designers. Einstein was also a profoundly rigorous thinker
with a deep sense of empirical inquiry. This fact interests far fewer
designers than Einstein's love of imagination.

If you want to read want Einstein himself has to say on speculation,
heuristic inquiry, empiricism, and imagination, three important works
are currently in print. His breakthrough articles of 1905 are
available in Einstein Miraculous Year (Einstein 1998 [1905]). His
major autobiographical statement is available in Paul Schilpp's (1969
[1949]) great anthology of writings on Einstein's science and
philosophy. These were published together with Einstein's own
autobiography, replies, and a comprehensive bibliography of
Einstein's publications. The third is Einstein's (1993 [1954]) own
popular explanation of relativity theory, first published in 1916,
translated and revised several times since.

Speculation, imagination, and heuristic inquiry in Einstein's work
were intimately related to empirical inquiry. At least, this is what
Einstein himself had to say on the matter.

Einstein's imaginative breakthroughs in relativity came about because
of his powerful physical intuition. Physical intuition involves a
deep understanding of the physical universe and an intimate knowledge
of the physics that preceded his own. This includes understanding the
deep implications of prior science.

One good example of this is the way that some of Einstein's ideas on
relativity derived from Maxwell's equations. These equations
contained powerful implications waiting to be understood. Einstein
understood them. Einstein's original insight involved a series of
questions implicit in the earlier physics that Einstein mastered and
probed.

Imaginative and speculative inquiry is important for progress in all
fields. At the same time, every field is plagued by idle speculation
and weird ideas wafting into the air on any conceivable theme. Since
fruitful speculation is the source of progress and development, we
should encourage it and attend to speculative inquiry. Since idle
speculation is a waste of time, we must at some point distinguish the
fruitful from the idle. How are we to distinguish between the two
forms of speculation?

In an essay titled "how can we be sure that Albert Einstein was not a
crank?" physicist Jeremy Bernstein (1993: 15-27) addresses precisely
this issue. Bernstein asks how we can distinguish between the idle
speculation of crank research and the fruitful speculation of the
innovator.

Bernstein proposes two criteria to separate the production of a crank
from the real thing. One criterion is "correspondence." The other is
"predictiveness."

Correspondence involves the ways in which a new proposal melds with
prior art, how a new theory explains the earlier theories and models
at a deeper and richer level. "I would insist," writes Bernstein
(1993: 18) "that any proposal for a radically new theory in physics,
or in any other science, contain a clear explanation of why the
precedent science worked. What new domain of experience is being
explored by the new science, and how does it meld with the old?"

Einstein launched his revolutionary work by demonstrating
correspondence with the physics people knew. His perception was new,
his conceptions were new, and his proposals reframed prior art.
Einstein did not end Newton's physics. He reframed it. The quantum
physics that so disturbed Einstein did not end Einstein's physics. It
grew from Einstein's work.

Einstein himself had an intriguing view of the relationship between
experience and theory - that is, the relationship between practice
and research. He held a nearly Pythagorean view of mathematics. While
the mathematics must correspond to reality, he did his work in the
mind rather than in the laboratory. This is where predictive power
arises.

Einstein proposed specific tests that could disprove his theories and
his models. This gave them predictive power. When the tests were
carried out, his theory was demonstrated as plausible. While
predictiveness is not possible in design in the same sense that it is
possible in physics, testing and reasoned response to results is
possible. At issue here is the fact that Einstein demanded that his
own speculative ideas be subject to critical inquiry and testing
before even he was ready to accept them fully. While he is famous for
confidence that his theories would pass the test, he also set the
test and asked for empirical evidence.

Einstein frequently referred to the importance of critical reasoning
based on empirical evidence and rigorous thinking. He frequently
discusses the role that empiricism played in his development. For one
crucial advance in special relativity theory, Einstein writes that
the, "type of critical reasoning which was required for the discovery
of this central point was decisive furthered, in my case, by the
reading of David Hume's and Ernst Mach's philosophical writings"
(Einstein 1969 [1949]: 53).

He was also a careful and rigorous student of earlier work. Those who
have seen the notes that Einstein took in his own doctoral studies
will discover "the notes of a conscientious student with a clear
understanding of the physics that preceded his own." This stands in
great contrast with the insistence on pure speculation unanchored in
anything other than private thought: "The typical crank appears to
regard all this apprenticeship as beneath his intellectual dignity.
He wants to go right to the head of the class. No apprenticeship for
him." (Bernstein 1993: 27)

Einstein's work was a triumph of imagination. This triumph was based
on the deep relationship between Einstein's work, the empirical
world, and earlier work. Einstein was always open to imaginative
ideas. He had little time for solipsistic thinkers who failed to
engage the larger field in rigorous inquiry.

To learn more on how Einstein and his ideas came to change the world
of physics, you might read Abraham Pais's (1982) biography or Jeremy
Bernstein's (2001) consideration of Einstein's work and influence.

If you are interested to know more about the role of imagination in
Einstein's physics, Pais and Bernstein have described his work and
its influence extensively, including serious attention to the role
that speculation, imagination, and heuristic inquiry play in
Einstein's ideas. Einstein himself also wrote on this.

Physicists today behave in much the same way that they did then.
There is speculation. There is also robust debate. The width and
breadth of inquiry and the power of the imagination is artistic. The
level of debate and inquiry is far different, however. It requires
deep knowledge of earlier work and it demands rigorous thinking.

The power of imagination in Einstein's work involved looking at what
everyone else had seen and understanding what no one before him had
ever understood. This rests on the deep and rigorous knowledge that
give rise to fruitful imagination.

Rob's comments deserve a note, too. Einstein's work shaped the
science that underlies many kinds of products. These include the
electric eye door opener and all technologies based on the
photoelectric effect, along with masers, lasers, klystrons, and a
whole lot more.

On the other hand, it took engineers and designers to bring these
products to life. Einstein's gift to design was more than a
hard-to-trace quote on imagination. Einstein's gift to design was the
science that paved the way for some of the most useful products in
today's world.

Yours,

Ken
