There is no general reason to expect evolution to be progressive – even in the weak, value-neutral sense. There will be times when increased size of some organ is favoured and other times when decreased size is favoured. Most of the time, average-sized individuals will be favoured in the population and both extremes will be penalised. During these times the population exhibits evolutionary stasis (i. e., no change) with respect to the factor being measured. If we had a complete fossil record and looked for trends in some particular dimension, such as leg length, we would expect to see periods of no change alternating with fitful continuations or reversals in direction – like a weathervane in changeable, gusty weather.

Let us not despair; it is a blessed cause, and success, ere long, will crown our exertions. Already we have gained one victory; we have obtained, for these poor creatures, the recognition of their human nature, which, for a while was most shamefully denied. This is the first fruits of our efforts; let us persevere and our triumph will be complete. Never, never will we desist till we have wiped away this scandal from the Christian name, released ourselves from the load of guilt, under which we at present labour, and extinguished every trace of this bloody traffic, of which our posterity, looking back to the history of these enlightened times, will scarce believe that it has been suffered to exist so long a disgrace and dishonour to this country.

You may not be her first, her last, or her only. She loved before she may love again. But if she loves you now, what else matters? She's not perfect-you aren't either, and the two of you may never be perfect together but if she can make you laugh, cause you to think twice, and admit to being human and making mistakes, hold onto her and give her the most you can. She may not be thinking about you every second of the day, but she will give you a part of her that she knows you can break-her heart. So don't hurt her, don't change her, don't analyze and don't expect more than she can give. Smile when she makes you happy, let her know when she makes you mad, and miss her when she's not there.

God has permitted and does permit us to be shaken by adversity. Difficult times lie ahead. We will be greatly tested. We have to take this warning seriously and live spiritually... Many saints would have loved to have lived in our times and have had our chance to struggle for Christ... Our struggle matters because it is not a struggle against an Ali Pasha, or a Hitler and a Mussolini, but a struggle against the devil himself. For this reason, our wages will be heavenly... The saints will become more holy and the vile will become more vile. Yet I feel great consolation inside. This is only a storm; like past storms, it will pass. May the Good God take evil and turn it into good. Amen.

Darwin himself told us in his last book (The Formation of Vegetable Mould Through the Action of Worms) that we should never underestimate the power of worms on the move.... The inversion of a humble worm, especially when disturbed, may bring down empires. Shakespeare told us that "the smallest worm will turn being trodden on." And Cervantes wrote in his author's preface to Don Quixote that "even a worm when trod upon, will turn again." ...Geoffrey, it seems, was correct after all - not in every detail, of course, but at least in basic vision and theoretical meaning. And the triumph of surprise, the inversion of nuttiness to apparent truth, stands as a premier example of the most exciting general development in evolutionary theory during our times.

In no particular order, I could not or would not exist without air, food, water, gravity, tides, the moon, the sun, night, civilization, the laws of physics, the laws of thermodynamics, the law of the land, ancestors having sex, DNA, viruses, bacteria, plants, animals, oceans, ice caps, the kindness of strangers, the Big Bang, familial bonds, smart people, brave people, memory, medicine, the periodic table of elements, tribal instincts, magnetic fields, weather, Earth's molten core, a rotating Earth, a tilted Earth, tectonic plates, sleep, death, heat, consciousness, evolution, teachers and the miraculous, self-regulating chemical factory that is my body. Other than that, I like to think of myself as a self-made man.
