“There are no physical problems—only mental ones.”

“Deep in the human nature there is an almost irresistible tendency to concentrate physical and mental energy on attempts at solving problems that seem to be unsolvable.”

Ragnar Frisch (1895–1973) Norwegian economist

“What most people do not know is that underlying every physical ailment is an underlying problem in consciousness. Another way of saying this is that there is a mental and emotional root to all physical ailments.”

Teal Swan (1984) American spiritual teacher

“It is only because of problems that we grow mentally and spiritually.”

M. Scott Peck (1936–2005) American psychiatrist

“Some pains are physical, and some pains are mental, but the one that's both is dental.”

Ogden Nash (1902–1971) American poet

“The mental never influences the physical. It is always the physical that modifies the mental, and when we think that the mind is diseased, it is always an illusion.”

Claude Bernard (1813–1878) French physiologist

“What makes old age hard to bear is not the failing of one's faculties, mental and physical, but the burden of one's memories.”

W. Somerset Maugham (1874–1965) British playwright, novelist, short story writer

“One who fails to observe mental and physical phenomena every time they arise cannot see them as merely mental and physical phenomena. Furthermore, one does not realize their causality, impermanence, unsatisfactoriness, notself, or their immediate disappearance upon arising and their continuous disappearance thereafter. Therefore, one mistakenly identifies these mental and physical phenomena with a personal entity, a person who is either born without any cause or created by a creator. One mistakes them for someone or something permanent and pleasant, everlasting, and unchanging.”

Mahasi Sayadaw (1904–1982) Burmese Buddhist philosopher

“Physical attractions are common. A mental connection is rare.”

Ralph Smart

“[T]he material of science is coextensive with the whole life, physical and mental, of the universe, and... the limits to our perception of the universe are only apparent, not real.”

Karl Pearson book The Grammar of Science
