I mentioned in the comments that I found this Introduction challenging. The writing is dense, but beyond that, Stengers seems to be breaking new (to me at least) conceptual ground by trying to write non-dualistically about a subject (science versus . . . everything else) that has always been configured as a dualism & for which we hardly have a non-dual vocabulary. As a consequence, she is of necessity forging a new conceptual language as she goes. Much of that effort proceeds by taking over Whitehead's term adventure, as in the title of his book, Adventures of Ideas. [Added later] In this attempt to find a way of speaking, Stengers offers a striking parable about an old Bedouin on his deathbed faced with the task of dividing his wealth among his three sons. He does so by bequeathing 1/2 his wealth to his eldest, 1/4 to the middle son & 1/6th to the youngest boy. The problem is that the old man's wealth is quantized in the form of eleven camels. After thus arranging his affairs, the old man dies, leaving his sons not only some camels, but a problem. Stengers tells us in this same chapter how an adventure, in Whitehead's usage, always begins with a problem--& I would add, a certain imaginative openness to the universe of possible solutions. The brothers are faithful sons & they feel bound to honor their father's last will & testament, but no amount of arithmetic leads to a solution, so they consult a village elder, who solves the problem by giving the brothers his sickly old camel, bringing the total to twelve, thus making the problem in arithmetic trivial. The accept the gift, divide the camels, then out of charity (one supposes) they return the wise man's camel to him & go on their way with clear consciences. The elder's offer of his camel was an adventure. Before the problem could be solved--or even sensibly addressed--a logjam in the brothers' thinking had to be broken up. The elder's offer of his camel solved this problem by creating a moral placeholder (a kind of necessary fiction) just long enough to break up the blockage in the brothers' thinking that allowed them to proceed. But isn't this merely a kind of legerdemain on the elder's part? If so, does it matter? There must also be other destinations this adventure could lead to--How many? And if we can think of others why do we find this one so satisfying? Perhaps because it is structured like a joke & a good joke can have a psychologically liberating effect. But doesn't the solution to the problem created by the awkward inheritance seem like a bit of a cheat? A clever & humorous bit of dishonesty, but a cheat nevertheless? [End of added material] One way of undertaking this adventure would be to imagine ourselves at a time before science and then to imagine what the world would have been like. If we were to undertake such an adventure we would have to be careful not to import our post-scientific vocabulary and to freely speculate as to the conditions that would prevail. I think that one of the things Stengers is proposing is a kind of imaginative or provisional form of thought that she names speculative, or speculation. This, she suggests, is what Whitehead does in his "speculative metaphysics," something supposedly banished by the power of analytical philosophy. In this mode, when one is confronted by a problem, one imagines a situation in which the problem might yield to insight. (This is what happens in the parable of the camels.) As preparation for teaching my Modern Poetry course online next semester, I have been rereading Wallace Stevens, with a view to trying to explain to students something about his "project," though he would never have conceived of his writing in such a way. In any case, it's possible to read Stevens--necessary, in fact, to read him so--as sweeping away dualisms & replacing them with a field that he calls imagination. That move opens up several directions of freedom--of play, in all all its meanings: the play of a serious child, but also the necessary play in a pulley or other machine that is necessary for it to operate effectively. It is like placing a jar in Tennessee. Then, the "slovenly wilderness" can organize itself, if only temporarily or provisionally, around the act of our placing the jar, which is an act of imagination. There is much more to say, but this will have to do for now. . .
