Title: If a tree falls in a forest
Content:  Canadian singer-songwriter, social activist and environmentalist Bruce Cockburn poses the question in the chorus of his song "If a Tree Falls," on his 1988 album Big Circumstance. Cockburn's lyrics frame it a pressing question regarding the cause and effect of deforestation. Washington-state-based wilderness conservatory Northwest Trek used a shortened form of the quote in its mid-1970s television advertisement, as such: "There is no sound unless someone is there to see it or hear it. Experience it at Northwest Trek." A paraphrase of the quote ("When you're falling in a forest and there's nobody around / Do you ever really crash, or even make a sound?") forms the bridge of the protagonist's solo

And gave a more technical answer, "Sound is vibration, transmitted to our senses through the mechanism of the ear, and recognized as sound only at our nerve centers. The falling of the tree or any other disturbance will produce vibration of the air. If there be no ears to hear, there will be no sound." The current phrasing appears to have originated in the 1910 book Physics by Charles Riborg Mann and George Ransom Twiss. The question "When a tree falls in a lonely forest, and no animal is near by to hear it, does

Content:  While the origin of the phrase is sometimes mistakenly attributed to George Berkeley, there are no extant writings in which he discussed this question. The closest are the following two passages from Berkeley's A Treatise Concerning the Principles of Human Knowledge, published in 1710: But, say you, surely there is nothing easier than for me to imagine trees, for instance, in a park, or books existing in a closet, and nobody by to perceive them. The objects of sense exist only when they are perceived; the trees therefore are in the garden... no longer than while there is somebody by to perceive them. Despite these passages bearing a distant resemblance to the

The song itself discusses a feeling of isolation through fear of failing in social interactions, as a part of the main character's social anxiety disorder. In LucasArts adventure game Monkey Island 2: Le Chuck's Revenge, Guybrush Threepwood meets Herman Thootrot on Dinky Island. In their dialogue the young pirate asks Herman to teach him philosophy. His lesson - humorously - focuses on solving this Zen puzzle: "If a tree falls in the forest, and none is around to hear it ... what color is the tree?" Making reference to this concept.

Content:  definition of sound, simplified, is a hearable noise. The tree will make a sound, even if nobody heard it, simply because it could have been heard. The answer to this question depends on the definition of sound. We can define sound as our perception of air vibrations. Therefore, sound does not exist if we do not hear it. When a tree falls, the motion disturbs the air and sends off air waves. This physical phenomenon, which can be measured by instruments other than our ears, exists regardless of human perception (seeing or hearing) of it. Putting together, although the tree falling on the island sends off air waves, it does not produce sound if no human is within the distance where the air waves are strong enough for a human to perceive them. However, if we define sound as the waves themselves, then sound would be produced.

Content:  Berkeley never actually proposed the question itself. However, his work did deal extensively with the question of whether objects could continue to exist without being perceived. In June 1883, in the magazine The Chautauquan, the question was asked, "If a tree were to fall on an island where there were no human beings would there be any sound?" They then went on to answer the query with, "No. Sound is the sensation excited in the ear when the air or other medium is set in motion." The magazine Scientific American corroborated the technical aspect of this question, while leaving out the philosophic side, a year later when they asked the question

A few decades before Alciato first published his emblem, Aesop's fable had served as basis for an independent version by Laurentius Abstemius in his Hecatomythium, published in the 1490s. Numbered 65, De nuce, asino et muliere describes how a woman asked the abused tree 'why it was so foolish as to give more and better nuts when struck by more and stronger blows? The tree replied: Have you forgotten about the proverb that goes: Nut tree, donkey and woman are bound by a similar law; these three things do nothing right if you stop beating them.' The moral that

Title: If a tree falls in a forest
Content:  Can something exist without being perceived by consciousness? – e.g. "is sound only sound if a person hears it?" The most immediate philosophical topic that the riddle introduces involves the existence of the tree (and the sound it produces) outside of human perception. If no one is around to see, hear, touch or smell the tree, how could it be said to exist? What is it to say that it exists when such an existence is unknown? Of course, from a scientific viewpoint, it exists. It is human beings that are able to perceive it. George Berkeley in the 18th century developed subjective idealism, a metaphysical theory to respond to these questions, coined famously as "to be is to be perceived". Today, meta-physicists are split. According to substance theory, a substance is distinct from its properties, while according to bundle theory, an object is merely its sense data.
