Oh ignorant, self-seeking cupidity which spurs us so in the short mortal life and steeps us so through all eternity!

Dante Alighieri, The Divine Comedy

Modern science has been a voyage into the unknown, with a lesson in humility waiting at every stop. Many passengers would rather have stayed home.

Carl Sagan

Our history is as much a product of torsion and stress as it is of unilinear drive. It is amusing that at any given point of time we haven't the slightest idea of what is happening to us. The present wars and ideological changes of nervousness and fighting seem to have direction, but in a hundred years it is more than possible it will be seen that the direction was quite different from the one we supposed.The limitation of the seeing point in time, as well as in space, is a warping lens.

John Steinbeck,  The Log from the Sea of Cortez

Ideas are not dangerous unless they find seeding place in some earth more profound than the mind…. dangerous only when planted in unease and disquietude. But being so planted, growing in such earth, it ceases to be idea and becomes emotion and then religion. 

John Steinbeck,  The Log from the Sea of Cortez

Educating the electorate in the limits of executive power. No one wants to believe it. And anyway, in a democracy there's always an opposition to tell them that anything is possible.

P.A. James, A Taste for Death

Eloquence and erudition were the twin prerequisites of greatness ... any effort expended in the cultivation of such gifts would surely be rewarded, if not in this world then in the world to come.

Catherine Nicholson, on Milton in the NYR. 

Men do not know the natural disease of the mind; it does nothing but ferret and inquire, and is eternally wheeling, juggling, and perplexing itself like silkworms, and then suffocates itself in its work;  It thinks it discovers at a great distance, I know not what glimpses of light and imaginary truth: but whilst running to it, so many difficulties, hindrances, and new inquisitions cross it, that it loses its way, and is made drunk with the motion.

Montaigne

Though all that has arrived, by report, of our knowledge of times past should be true, and known by some one person, it would be less than nothing in comparison of what is unknown. And of this same image of the world, which glides away whilst we live upon it, how wretched and limited is the knowledge of the most curious; not only of particular events, which fortune often renders exemplary and of great concern, but of the state of great governments and nations, a hundred more escape us than ever come to our knowledge.

Montaigne

I leave the choice of my arguments to fortune, and take that she first presents to me; they are all alike to me, I never design to go through any of them; for I never see all of anything…. Of a hundred members and faces that everything has, I take one, one while to look it over only, another while to ripple up the skin, and sometimes to pinch it to the bones: I give a stab, not so wide but as deep as I can, and am for the most part tempted to take it in hand by some new light I discover in it.

Michel de Montaigne

Ecology and evolution are deeply intertwined. Just as the death and decay of organisms provide raw materials for subsequent generations, so too the deaths of species spawn new possibilities for future generations of species. Without extinction, there would be insufficient ecological space for evolution to explore alternative solutions and diversify into new life forms. When initially faced with some change to their native environments, species don’t grimly stay put and evolve into new forms better suited to the transformed conditions. They move, tracking the old habitat. In general, it’s only when the old habitat disappears that species are forced to adapt or die. Mass extinctions—the dying off of multiple, distantly-related lineages over vast areas in a short span of time—occur when one or more external forces wipe out a range of habitats, cutting off opportunities for tracking habitats.  Over the past half-billion  years, there have been five major mass extinctions, with the dinosaurs wiped out in the most recent of these. We now face the sixth mass extinction, which threatens to tear apart the fabric of the biosphere, with drastic consequences for most life on this planet, including us. In better times, species losses tick along at a barely discernable rate—perhaps one every five years. At present, somewhere between 50 and 150 species disappear every day, never to be seen again.... This time around, a single species—Homo sapiens—has become the external force driving the decimation of millions of other species. Yes, we are the asteroid now colliding with the planet.

Nothing is so firmly believed, as what we least know; nor any people so confident, as those who entertain us with fables.

Michel de Montaigne

There isn’t anything so grotesque or so incredible that the average human being can’t believe it.


Mark Twain, as quoted in The Consciousness Deniers, Galen Strawson (NYRB, March 13, 2018)

We know the meaning of nothing but the words we use to describe it.

Anthony Marra, A Constellation of Vital Phenomena

They were people who had no doubt whatsoever that the more narrow-minded they became, the closer they got to heaven.

Haruki Murakami, 1Q84
