“The most reliable joy is to be out of doors, to be a creature among other creatures. I find it very restful.”

Context: According to my observations, mankind are among the most easily tamable and domesticable of all creatures in the animal world. They are readily reducible to submission, so readily conditionable (to coin a word) as to exhibit an almost incredibly enduring patience under restraint and oppression of the most flagrant character. So far are they from displaying any overweening love of freedom that they show a singular contentment with a condition of servitorship, often showing a curious canine pride in it, and again often simply unaware that they are existing in that condition.

Context: Man is innately a creature of love. That love is the most powerful force in the universe, and eventually — it's a very slow process — it will conquer. I think there will come a time, and this is down the road a great many years, when civilized people will look back in horror on our generation and the ones that have preceded it: the idea that we should eat other living things running around on four legs, that we should raise them just for the purpose of killing them! The people of the future will say “meat-eaters!” in disgust and regard us in the same way that we regard cannibals and cannibalism.

The Sixteenth Revelation, Chapter 76
Context: In this blissful Shewing of our Lord I have understanding of two contrary things: the one is the most wisdom that any creature may do in this life, the other is the most folly. The most wisdom is for a creature to do after the will and counsel of his highest sovereign Friend. This blessed Friend is Jesus, and it is His will and His counsel that we hold us with Him, and fasten us to Him homely — evermore, in what state soever that we be; for whether-so that we be foul or clean, we are all one in His loving. For weal nor for woe He willeth never we flee from Him. But because of the changeability that we are in, in our self, we fall often into sin. Then we have this by the stirring of our enemy and by our own folly and blindness: for they say thus: Thou seest well thou art a wretched creature, a sinner, and also unfaithful. For thou keepest not the Command; thou dost promise oftentimes our Lord that thou shalt do better, and anon after, thou fallest again into the same, especially into sloth and losing of time. (For that is the beginning of sin, as to my sight, — and especially to the creatures that have given them to serve our Lord with inward beholding of His blessed Goodness.) And this maketh us adread to appear afore our courteous Lord. Thus is it our enemy that would put us aback with his false dread, of our wretchedness, through pain that he threateth us with. For it is his meaning to make us so heavy and so weary in this, that we should let out of mind the fair, Blissful Beholding of our Everlasting Friend.
