Unperceived Existence Is Not Possible

If I do not perceive a thing, then in my perspective, the thing does not exist.Argument. Assume I do not perceive a thing. Name the thing t. Ultimately, I do not have enough evidence for the existence of t. Since that negative truth is ultimate, in my perspective, t does not exist. In a previous debate[1] I instigated, I used that argument to deny the possibility of unperceived existence.To build on the idea of the previous paragraph, it seems that: a proposition is provable if and only if it is true. In a previous debate[2] I instigated, I argued that: a proposition is logically provable if and only if it is true. The assumption that I don't perceive t suggests that I can't prove that in my perspective, t exists. It seems perception of a thing is required for proof of it. It seems that if a thing is proved, then it is perceived. It follows by the suggestion that the proposition "in my perspective, t exists" is unprovable and the thesis "a proposition is provable if and only if it is true" that the proposition "in my perspective, t exists" is false. So it's suggested that in my perspective, t does not exist.The mere assumption that I do not perceive t is evidence in support of the truth of the proposition "in my perspective, t does not exist." No matter how much evidence there is, and no matter how strong the evidence is in support of the truth of the negation of the proposition "in my perspective, t does not exist," there is still evidence in support of the truth of the proposition "in my perspective, t does not exist." The previous sentence suggests that in my perspective, t does not exist.No eyewitness accounts of a person who is not I, no photographs, no videos, and no approximate yet inexact evidence[3] can be reliable enough to prove to me that t exists. No eyewitness accounts of a person who is not I, no photographs, no videos, and no approximate yet inexact evidence would give me proof to a high enough or to the highest level of certainty that t exists. People can lie about the existence of t, a photograph or video can depict a fictitious or fake thing, and approximate yet inexact evidence can mislead. The probability of deception by people, photographs, videos, or approximate yet inexact evidence is never zero, no matter how close to zero it is. The probability of error made through examination of people, photographs, videos, or approximate yet inexact evidence is never zero, no matter how close to zero it is.Another argument considers a legal perspective. In a jury trial, if there is not enough evidence to prove beyond a reasonable doubt that an alleged criminal committed a crime, then he must be found not guilty.[4][5] That principal, together with the presumption of innocence, suggest that from a legal perspective, if there is not enough evidence to prove beyond a reasonable doubt that an alleged criminal committed a crime, then he did not commit the crime. It is thus further suggested that since there is not enough evidence to prove with certainty that in my perspective, t exists, in my perspective, t does not exist.ENDNOTES:[1] "Unperceived Existence Is Not Possible," http://www.debate.org...[2] "A Proposition Is Logically Provable If and Only If It Is True," http://www.debate.org...[3] Approximate yet inexact evidence may be temporally or spatially close to, but not exactly coinciding with what is suggested by the evidence. For example, prints in dirt resembling coyote paw prints are approximate yet inexact evidence that a coyote was present, but the evidence is not good enough to conclude with certainty that a coyote was present. The prints could have been made in some other way.[4] The last sentence of page 1 of "PROOF BEYOND A REASONABLE DOUBT," which is a model jury instruction for the Massachusetts District Court and is located at http://www.mass.gov...[5] The sentence that begins on page 5 and ends on page 6 of "VIOLATION OF A HARASSMENT PREVENTION ORDER," which is another model jury instruction for the Massachusetts District Court and is located at http://www.mass.gov...
