The name Theory of Evolution in Chinese / Japanese...

進化論 can be translated as “Darwin's theory of evolution,” “evolutionary theory,” or “theory of evolution.”

Same translation for Chinese, Japanese, and old Korean. Therefore, this title is very universal.

根性論 is a Japanese title that refers to the belief that where there's a will, there's a way.

Another way to translate this is “The Guts Theory” or “The Doctrine of Will-Power.” Maybe breaking down the meaning of the characters will help clarify this:
根性 = will-power; guts; temper; nature; spirit; nature and character; the nature of the powers of any sense.
論 = theory; doctrine; treatises on dogma, philosophy, discipline, etc.

進化 means evolution in Chinese, Japanese Kanji, and old Korean Hanja.

Sometimes it can mean progress, and in Japanese, it can be the female given name, Shinka.

演化 means to evolve or evolution in Chinese.

The first character means to develop, evolve, practice, perform, or extend.

The second character means to make into, to change into, to transform, or to metamorphose.

理念/理唸 means idea, notion, concept, principle, theory, philosophy*, or doctrine in Chinese, Japanese Kanji, and old Korean Hanja.

This word is OK for a wall scroll, although it's more commonly used as an oral/informal word in Asia.

* This is not the title for philosophy but rather is about having a certain philosophy or approach to something.

Depending on the romanization scheme you use, this man's name can be spelled Laozi, Lao Tzu, or Lao Tze. In older English usage, he was known as Laocius. He is believed to have lived around 500 B.C.

He was a Chinese philosopher, founder of Daoism/Taoism, credited with being the author of the sacred and wise book of Daoism/Taoism.

There is a theory that Lao Tzu's soul traveled to India and was reborn as the Buddha.

不來不去 is a Buddhist term, originally anāgamana-nirgama from Sanskrit.

This implies that things are neither coming into nor going out of existence.

This can also mean “all things are eternal,” or others will call this the Buddhist concept of the eternal conservation of energy.

This theory predates Albert Einstein and Isaac Newton.

Note: 不來不去 is not a well-known word for both Buddhists and non-Buddhists, so not all will recognize it.

空 is a single character that means empty, void, hollow, vacant, vacuum, blank, nonexistent, vacuity, voidness, emptiness, non-existence, immateriality, unreality, the false or illusory nature of all existence, and being unreal.

In the Buddhist context, this relates to the doctrine that all phenomena and the ego have no reality but are composed of a certain number of skandhas or elements, which disintegrate. The void, the sky, space. The universal, the absolute, complete abstraction without relativity. The doctrine further explains that all things are compounds, or unstable organisms, possessing no self-essence, i.e. are dependent, or caused, come into existence only to perish. The underlying reality, the principle of eternal relativity, or non-infinity, i.e. śūnya, permeates all phenomena making possible their evolution.

From Sanskrit and/or Pali, this is the translation to Chinese and Japanese of the title śūnya or śūnyatā.

In Japanese, when pronounced as “ron” (sounds like “roan”) this can be a given name. It should be noted that this Kanji has about 5 different possible pronunciations in Japanese: kuu, kara, sora, ron, and uro. 空 is also an element in the Japanese version of the five elements.

虚実 is a Japanese word that means “falsehood [and] truth” or “fiction [and] fact.”

This concept is used in warfare, gameplay, and martial arts strategies. 虚実 can be a strategy of real and/or deceptive moves. This gets to some Sun Tzu Art of War stuff where in warfare a strategic move is either a real and serious move or it is a deceptive blow.

Let's explore each character in more depth:

虚 was originally written 虛 (there is a very subtle difference in the strokes at the bottom of the character) and means unpreparedness, falsehood, emptiness, void, abstract theory, empty or unoccupied, diffident or timid, false, humble or modest, virtual, or in vain.
In the Buddhist context, 虛 represents the Pali/Sanskrit word “śūnya,” meaning empty, vacant, unreal, unsubstantial, untrue, space, humble, or in vain.
In ancient Eastern/Chinese astronomy, 虛 represents the “Emptiness” constellation (one of the 28 mansions in the sky).

実 was originally 實 in Chinese (they currently write it as 实 in Simplified Chinese) with the meaning, truth, reality, sincerity, honesty, fidelity, and substance.
The Buddhist context is similar, adding real, true, honest, really, solid, definitely, sincere, solid, fixed, full, to fill, fruit, kernel, verily, in fact, the supreme fact, or ultimate reality to the definition.
