A man has a property in his opinions and the free communication of them.
He has a property of peculiar value in his religious opinions, and in the profession and practice dictated by them.
He has a property very dear to him in the safety and liberty of his person.
He has an equal property in the free use of his faculties and free choice of the objects on which to employ them.
In a word, as a man is said to have a right to his property, he may be equally said to have a property in his rights.

Every man has a property in his person, This nobody has a right to, but himself.

Wealth is the product of man's capacity to think.

Funny thing how it is. If a man owns a little property, that property is him, it's part of him, and it's like him. If he owns property only so he can walk on it and handle it and be sad when it isn't doing well, and feel fine when the rain falls on it, that property is him, and some way he's bigger because he owns it. Even if he isn't successful he's big with his property. That is so.'

'But let a man get property he doesn't see, or can't take time to get his fingers in, or can't be there to walk on it - why, then the property is the man. He can't do what he wants, he can't think what he wants. The property is the man, stronger than he is. And he is small, not big. Only his possessions are big - and he's the servant of his property. That is so, too.

As much land as a man tills, plants, improves, cultivates, and can use the product of, so much is his property.

A man is but the product of his thoughts. What he thinks, he becomes.

For the activity of the mind is life

Thought is the property of him who can entertain it, and of him who can adequately place it.

Scotus... declares that a man’s knowledge is measured by the amount of his mental activity...

A person's mental activities are entirely due to the behavior of nerve cells, glial cells, and the atoms, ions, and molecules that make them up and influence them.

A man is literally what he thinks, his character being the complete sum of all his thoughts.

"From all which it is evident, that though the things of nature are given in common, yet man, by being master of himself, and " proprietor of his own person, and the actions or labour of it, had still in himself the great foundation of property;" and that which made up the greater part of what he applied to the support or comfort of his being, when invention and arts had improved the conveniencies of life, was perfectly his own, and did not belong in common to others."
