“Great thoughts reduced to practice become great acts.”

A Propos of Lady Chatterley's Lover (1929)
Context: We are today, as human beings, evolved and cultured far beyond the taboos which are inherent in our culture. This is a very important fact to realise. Probably, to the Crusaders, mere words were potent and evocative to a degree we can't realise. The evocative power of the so-called obscene words must have been very dangerous to the dim-minded, obscure, violent natures of the Middle Ages, and perhaps are still too strong for slow-minded, half-evoked lower natures today. But real culture makes us give to a word only those mental and imaginative reactions which belong to the mind, and saves us from violent and indiscriminate physical reactions which may wreck social decency. In the past, man was too weak-minded, or crude-minded, to contemplate his own physical body and physical functions, without getting all messed up with physical reactions that overpowered him. It is no longer so. Culture and civilisation have taught us to separate the reactions. We now know the act does not necessarily follow on the thought. In fact, thought and action, word and deed, are two separate forms of consciousness, two separate lives which we lead. We need, very sincerely, to keep a connection. But while we think, we do not act, and while we act we do not think. The great necessity is that we should act according to our thoughts, and think according to our acts. But while we are in thought we cannot really act, and while we are in action we cannot really think. The two conditions, of thought and action, are mutually exclusive. Yet they should be related in harmony.

Cassandra (1860)
Context: The great reformers of the world turn into the great misanthropists, if circumstances or organisation do not permit them to act. Christ, if He had been a woman, might have been nothing but a great complainer. Peace be with the misanthropists! They have made a step in progress; the next will make them great philanthropists; they are divided but by a line.
The next Christ will perhaps be a female Christ. But do we see one woman who looks like a female Christ? or even like "the messenger before" her "face", to go before her and prepare the hearts and minds for her?
To this will be answered that half the inmates of Bedlam begin in this way, by fancying that they are "the Christ."
People talk about imitating Christ, and imitate Him in the little trifling formal things, such as washing the feet, saying His prayer, and so on; but if anyone attempts the real imitation of Him, there are no bounds to the outcry with which the presumption of that person is condemned.
