From East of Eden:
It wasn't very long until all the land in the barren hills near King City and San Ardo was taken up, and ragged families were scattered through the hills, trying their best to scratch a living from the thin flinty soil. They and the coyotes lived clever, despairing, submarginal lives. They landed with no money, no equipment, no tools, no credit and particularly with no knowledge of the new country and no technique for using it. Surely such venture is nearly gone from the world. And the families did survive and grow. They had a tool or a weapon that is also nearly gone, or perhaps it is only dormant for a while. It is argued that because they believed thoroughly in a just, moral God they could put their faith there and let the smaller securities take care of themselves. But I think that because they trusted themselves and respected themselves as individuals, because they knew beyond doubt that they were valuable and potentially moral units--because of this they could give God their own courage and dignity and then receive it back. Such things have disappeared perhaps because men do not trust themselves any more, and when that happens there is nothing left except perhaps to find some strong sure man, even though he may be wrong, and to dangle from his coattails. (p.12, Penguin Centennial Edition)
I think the tool or weapon to which Steinbeck refers is in fact dormant. We will learn somehow to retrieve it. It must be rediscovered and chosen. Nothing is given anymore.
