The argument from ignorance, also known as appeal  

無知論證，也稱為訴諸無知

to ignorance or argumentum ad ignorantiam,  is a fallacy that occurs when something is  

或argumentum ad ignorantiam，是一種謬誤，當某件事

claimed to be true simply because it has  not been proven false, or vice versa.

僅僅因為尚未被證明是錯誤的而被聲稱是正確的時，就會發生這種謬誤，反之亦然。

This fallacy asserts that a lack of evidence  against a position is evidence for it,  

這種謬論聲稱，缺乏反對某個立場的證據就是支持該立場的證據，

or that an argument is necessarily false  because it has not been proven true.

或者某個論點必然是錯誤的，因為它尚未被證明是正確的。

Everyday Example:

日常例子：

An individual claims that there must be  life on other planets because no one has  

某人聲稱其他行星上一定有生命，因為沒有人能夠

been able to prove definitively that there isn't.

明確證明不存在生命。

In this instance, the person is basing  their belief on the absence of evidence  

在這種情況下，人們的信念是基於缺乏

to the contrary rather than on positive evidence  supporting the existence of extraterrestrial life.

相反的證據，而不是基於支持外星生命存在的積極證據。

This argument assumes that the lack of disproof is  equivalent to proof, which is a logical fallacy.

這種論證假設缺乏反證就等於證明，這是一個邏輯謬誤。
