Listen widely to remove your doubts and be careful when speaking about the rest and your mistakes will be few. See much and get rid of what is dangerous and be careful in acting on the rest and your causes for regret will be few. Speaking without fault, acting without causing regret: 'upgrading' consists in this.
I realise that man, in his imperfection, can commit innumerable errors - but to devote myself deliberately to errors, that is something I cannot do. I shall never come personally to terms with the Christian lie. Our epoch, in the next 200 years, will certainly see the end of the disease of Christianity. My regret will have been that I could not behold its demise.
Why was the human race created? Or at least why wasn't something creditable created in place of it? God had His opportunity. He could have made a reputation. But no, He must commit this grotesque folly - a lark which must have cost Him a regret or two when He came to think it over and observe effects.
Yet you shall not deplore having known blindness, nor regret having been deaf. For in that day you shall know the hidden purposes in all things. And you shall bless darkness as you would bless light.
The superior man accords with the course of the Mean. Though he may be all unknown, unregarded by the world, he feels no regret - It is only the sage who is able for this.
Humans — who enslave, castrate, experiment on, and fillet other animals — have had an understandable penchant for pretending animals do not feel pain. A sharp distinction between humans and 'animals' is essential if we are to bend them to our will, make them work for us, wear them, eat them — without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeelingly toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.
Oh! captive, bound, and double-ironed," cried the phantom, "not to know, that ages of incessant labour, by immortal creatures, for this earth must pass into eternity before the good of which it is susceptible is all developed. Not to know that any Christian spirit working kindly in its little sphere, whatever it may be, will find its mortal life too short for its vast means of usefulness. Not to know that no space of regret can make amends for one life's opportunity misused!
