“It has long been though that the sun is a constant star of regular and repeatable behavior. Measurements of the radiative output, or solar constant, seem to justify the first assumption, and the record of periodicity in sunspot numbers is taken as evidence of the second. Both records, however, sample only the most recent history of the sun.”

“The reality of the 'Maunder Minimum' and its implications of basic solar change may be but one more defeat in our long and losing battle to keep the sun perfect, or, if not perfect, constant, and if inconstant, regular. Why we think that sun should be any of these when other stars are not is more a question for social than for physical science.”

John A. Eddy (1931–2009) American astronomer

“I have reexamined the contemporary reports and new evidence which has come to light since Maunder's time and conclude that this 70-year period was indeed a time when solar activity all but stopped. This behavior is wholly unlike the modern behavior of the sun which we have come to accept as normal, and the consequences for solar and terrestrial physics seem to me profound.”

John A. Eddy (1931–2009) American astronomer

“It would seem that Maunder and Sporer were right and that most of the rest of us have been wrong. As is often the case in the onrush of modern science, we had too quickly forgotten the past, forgotten the less-than-perfect pedigree of the sunspot cycle and the fact that it too once came as a surprise. We had adopted a kind of solar uniformitarianism, contending that the modern behavior of the sun represented the normal behavior of the sun over a much longer span of time.”

“Outside intelligences, exploring the Solar System with true impartiality, would be quite likely to enter the Sun in their records thus: Star X, spectral class G0, 4 planets plus debris.”

“When we have observed the Sun most intensively, its behavior may have been unusually regular and benign.”

“When you claim that the universe started in this particular way you are making a very profound statement. If I make a statement saying that the sun started in a certain way, I would immediately be asked for proof that the sun started in that way. I will have to go around gathering evidence of w:Solar systems}Solar systems forming, stars forming. I will have to produce evidence saying that this is how new solar systems are being formed, so the sun must have been formed in the same manner. That is a reasonably credible assumption.”

Jayant Narlikar (1938) Indian physicist

Jayant Narlikar's Cosmology

“The sun is still the number 1 factor in our energy balance. No matter how much people argue about CO2, they can't successfully explain the pre industrial revolution 900-1300AD Medieval Warming Period or the cold 1645-1715 AD Maunder Sunspot Minimum that coincided with European crop failure, famine and disease while linking it with our modern day issues with CO2 to climate change. Yet sunspots and solar cycles can and do explain both.”

“A long record has been written. In that record, both in this State and in the national capital, you will find a simple, clear and consistent adherence not only to the letter, but to the spirit of the American form of government.”

1930s, Address at the Democratic State Convention, Syracuse, New York (1936)
Context: Desperate in mood, angry at failure, cunning in purpose, individuals and groups are seeking to make Communism an issue in an election where Communism is not a controversy between the two major parties.
Here and now, once and for all, let us bury that red herring, and destroy that false issue. You are familiar with my background; you know my heritage; and you are familiar, especially in the State of New York, with my public service extending back over a quarter of a century. For nearly four years I have been President of the United States. A long record has been written. In that record, both in this State and in the national capital, you will find a simple, clear and consistent adherence not only to the letter, but to the spirit of the American form of government.

Context: The great difficulty which history records is not that of the first step, but that of the second step. What is most evident is not the difficulty of getting a fixed law, but getting out of a fixed law; not of cementing (as upon a former occasion I phrased it) a cake of custom, but of breaking the cake of custom; not of making the first preservative habit, but of breaking through it, and reaching something better.
