What Is Thoughts Are Things About?

Thoughts Are Things gathers essays by Prentice Mulford, a former California miner and journalist who turned to writing about the mind. The book appeared in 1889, and the essays first came out in the 1880s. Mulford is counted among the pioneers of the New Thought movement.

The central claim, in Mulford’s words and view, is that thoughts are real forces. He teaches that what we think builds our moods, our health and our paths through life. He asks readers to guard their minds, drop fear, rest more and trust an inner source of strength. These are the author’s teachings, not proven facts.

Theme-by-Theme Study Notes

These notes are our own summary, written to help you follow the book. Each one ends with a small practice you can try this week.

1

Thoughts Are Things

Mulford teaches that every thought is a real force that goes out from you and has an effect. He says an idea held with feeling does not simply vanish. It shapes your mood, your health and the people around you. The essay invites you to treat your mind as a workshop, not a waiting room. Read this theme as the base for everything else in the book. If thoughts really are forces, then small daily choices about what to dwell on begin to matter a great deal.

Try it. Write down three thoughts you had today. Mark each one as building you up or wearing you down.
2

Thought and Success

Mulford describes success as the result of steady, positive thinking joined with calm effort. He argues that like draws like, so the mind you carry tends to meet matching people and events. He is often named as an early voice of what later became the law of attraction. He asks readers to hold a clear aim. The tone is hopeful and practical. Success here is not luck or hustle alone, but a steady habit of expecting good and working toward it with a settled, cheerful mind.

Try it. Pick one clear aim for the week. Write it in one sentence and read it each morning.
3

Mind and Body

The author teaches that worry, fear and anger weigh on the body, while peace and cheer support it. He treats the mind as a partner to physical well-being, not a separate matter. He is not giving medical advice, and neither does this guide. The point is to notice how mood and body move together. Mulford wants readers to become observers of their own moods, so they can see which thoughts leave them tired and which leave them light and ready for the day.

Try it. Notice one moment today when worry shows up in your body. Breathe slowly until it eases.
4

Letting Go of Worry

Mulford urges readers to stop feeding fear and anxious scenes in the mind. He describes worry as a habit that drains energy and calls in what you dread. His remedy is to drop the habit gently and turn attention to something steadier. He treats it as a daily choice, not a single event. The tone is firm but kind. Mulford does not shame the worrier. He simply says that attention is yours to direct, and that every calm minute makes the next one easier.

Try it. Each time worry starts, name it, set it down, and do one small useful thing instead.
5

The Value of Rest

The author describes rest as more than sleep. He teaches that a quiet, passive mind lets fresh strength flow in, and that constant hurry cuts people off from it. He invites readers to pause, be still and let tension go. Renewal, in his view, comes when we stop pushing. He pairs this with the idea that busy minds attract more busyness. Learning to be quiet, he says, is a skill worth practising, and the results show up in clearer thinking.

Try it. Sit for five quiet minutes with no phone. Let your shoulders drop with every exhale.
6

The Inner Source

Mulford writes that a greater intelligence lives inside each person and can be drawn on through stillness and trust. He describes this as an inner source of strength and guidance. This is the author’s spiritual view, offered as an invitation to look inward. He presents it as open to every reader. Notice that the claim is offered as personal experience and spiritual belief. Treat it as a question to explore in quiet moments, and judge it by whether it brings you steadiness.

Try it. Ask yourself one honest question tonight. Sit quietly and notice the first calm answer that arises.
7

Surroundings and Influence

The author teaches that the thoughts of others reach us, and that crowds, habits and places can leave a mark on our mood. He encourages readers to pick company and surroundings with care and to protect their own inner calm. He frames this as guarding, not hiding. The aim is not to avoid people, but to notice who leaves you drained and who leaves you stronger. Mulford says your inner state is worth defending, and that choosing wisely is a form of self-respect.

Try it. List the people and places that lift you. Plan one more visit with one of them this week.
8

Letting Go of Harmful Thoughts

Mulford calls for dropping harmful thoughts, grudges and unkind habits, so the mind can fill with better things. He argues that hate and resentment are costly to the one who holds them. The practice is to stop first, then build. It asks for honesty, not perfection. Mulford links this to everything before it. Clearing out bitterness frees energy for the hopeful, creative thoughts he wants readers to grow, so the stopping is a doorway, not a punishment.

Try it. Name one grudge you carry. Write one sentence of release and say it aloud once.
