From papa to Emily:
Your mind is on a track. There’s actually very little leeway between birth and death. The course is strikingly simple, though we don’t notice due to our one chance at living, and the fact that our perspective biases us to exaggerate what little difference there really is between one life and the next, and one generation to the next. Gender plays a role in the course we must live, as does age, though these aren’t very popular topics to discuss. But keep that in mind, and listen to what your nature has to say, even if you choose not to heed; for informed choice brings both responsibility and accountability into the hands of the chooser. Always apply reason to your biology, always demand diplomacy of your motives, always seek virtue of your wants, or deny them altogether. In this way, never hesitate to resist your nature should it prove base, barbarous, unjust, or inhumane.
So you’ll bump along this course of living, fortune heaving you at once to the left, and next to the right; but always forward, and at a steady rate, even when at rest, even when you decide not to choose. Remember that you’ll always be on those rails, and there’s nothing spiritual or spooky or inexplicable about them; so don’t get suckered into motivation, divination or exorcism to change your way. Instead, ride the rails like the successful survivor you have become, we have become, we’ve all become, by virtue of the simple fact we’re alive. You see, biology’s criteria for success is both simple and absolute. So ride your rails to the end of the line. And if you choose, pass carefully your successful mandate into the future, as your mother and I have done through our loving creation of you.
