The older woman's love is not love of herself, nor of herself mirrored in a lover's eyes, nor is it corrupted by need. It is a feeling of tenderness so still and deep and warm that it gilds every grass blade and blesses every fly. It includes the ones who have a claim on it, and a great deal else besides. I wouldn't have missed it for the world.
There is no other species on the Earth that does science. It is, so far, entirely a human invention, evolved by natural selection in the cerebral cortex for one simple reason: it works. It is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths; all assumptions must be critically examined; arguments from authority are worthless. Second: whatever is inconsistent with the facts must be discarded or revised. We must understand the Cosmos as it is and not confuse how it is with how we wish it to be.
