I would say apophatic theology does a fairly good job of demolishing fanciful definitions of God upon which some religions base their teachings. http://en.wikipedia.org/wiki/Apophatic_theology#Apophatic_description_of_God > Negative theology has a place in the Western Christian tradition as > well, although it is definitely much more of a counter-current to the > prevailing positive or cataphatic traditions central to Western > Christianity. For example, theologians like Meister Eckhart and St. > John of the Cross (San Juan de la Cruz), mentioned above, exemplify > some aspects of or tendencies towards the apophatic tradition in the > West. The medieval work, The Cloud of Unknowing and St. John's Dark > Night of the Soul are particularly well known in the West. There is also some similarity with this in Buddhism, in the [Diamond Sutra](https://en.wikipedia.org/wiki/Diamond_Sutra): > After these words, the venerable Subhûti spoke thus to Bhagavat: 'O > Bhagavat, how is this treatise of the Law called, and how can I learn > it?' After this, Bhagavat spoke thus to the venerable Subhûti: 'This > treatise of the Law, O Subhûti, is called the Pragñâ-pâramitâ > (Transcendent wisdom), and you should learn it by that name. And why? > Because, O Subhûti, what was preached by the Tathâgata as the > Pragñâ-pâramitâ, that was preached by the Tathâgata as no-Pâramitâ. > Therefore it is called the Pragñâ-pâramitâ. > > 'Then, what do you think, O Subhûti, is there anything (dharma) that > was preached by the Tathâgata?' Subhûti said: 'Not indeed, O Bhagvat, > there is not anything that was preached by the Tathâgata.' source: http://www.sacred-texts.com/bud/sbe49/sbe4929.htm
