The human mind is capable of excitement without the application of gross and violent stimulants; and he must have a very faint perception of its beauty and dignity who does not know this...

The remarkable thing about the human mind is its range of limitations.

Consider the human mind! It is capable of amazing feats when used properly. Conversely, without exercise it atrophies to a lump of gray-yellow fat.

Interruption, incoherence, surprise are the ordinary conditions of our life. They have even become real needs for many people, whose minds are no longer fed by anything but sudden changes and constantly renewed stimuli. We can no longer bear anything that lasts. We no longer know how to make boredom bear fruit. So the whole question comes down to this: can the human mind master what the human mind has made?

Personally, I do not believe the human mind has any limits but those we impose ourselves.

"The human mind is not a dignified organ, and I do not see how we can exercise it sincerely except through eclecticism. And the only advice I would offer my fellow eclectics is: "Do not be proud of your inconsistency. It is a pity, it is a pity that we should be equipped like this. It is a pity that Man cannot be at the same time impressive and truthful.

Most of us will be eclectics to this side or that according to our temperament. The human mind is not a dignified organ, and I do not see how we can exercise it sincerely except through eclecticism. And the only advice I would offer my fellow eclectics is: "Do not be proud of your inconsistency. It is a pity, it is a pity that we should be equipped like this. It is a pity that Man cannot be at the same time impressive and truthful."

An inner joyousness, amounting to ecstasy, is the normal condition of the genius mind. Any lack of that joyousness develops body-destroying toxins. That inner ecstasy of the mind is the secret fountain of perpetual youth and strength in any man. He who finds it finds omnipotence and omniscience.

The untrapped mind is open enough to see many possibilities, humble enough to learn from anyone and anything, forbearing enough to forgive all, perceptive enough to see things as they really are, and reasonable enough to judge their true value.

For this is our central human problem: that we are almost constantly the victims of our emotions, always being swept up and down on a kind of inner-switchback. We possess a certain control over them; we can 'direct our thoughts' -- or feelings -- in such a way as to intensify them. This is certainly our most remarkable human characteristic: imagination. Animals require actual physical stimuli to trigger their experience. A man can retreat into a book -- or a daydream -- and live through certain experiences quite independent of the physical world. He can even, for example, imagine a sexual encounter, and not only experience all the appropriate physical responses, but even the sexual climax. Such a curious ability is far beyond the power of any animal.

Give the brain encouragement from study, from thinking, from visualizing and no drugs are needed.

Unlike any other creature on this planet, humans can learn and understand, without having experienced. They can think themselves into other people’s places. Of course, this is a power, like my brand of fictional magic, that is morally neutral. One might use such an ability to manipulate, or control, just as much as to understand or sympathise. And many prefer not to exercise their imaginations at all. They choose to remain comfortably within the bounds of their own experience, never troubling to wonder how it would feel to have been born other than they are. They can refuse to hear screams or to peer inside cages; they can close their minds and hearts to any suffering that does not touch them personally; they can refuse to know. I might be tempted to envy people who can live that way, except that I do not think they have any fewer nightmares than I do. Choosing to live in narrow spaces leads to a form of mental agoraphobia, and that brings its own terrors. I think the wilfully unimaginative see more monsters. They are often more afraid. What is more, those who choose not to empathize enable real monsters; for without ever committing an act of outright evil ourselves, we collude with it, through our own apathy.

I can discover within me no power of perception which is not glutted with its proper pleasure, yet I do not feel myself delighted. Man has surely some latent sense for which this place affords no gratification, or he has some desires distinct from sense which must be satisfied before he can be happy.

The human mind can bear plenty of reality but not too much unintermittent gloom.
