There is the view which dismisses various arguments on account that those arguments are simply based on "anthropomorphizing" and that "anthropomorphizing" is in discord with reality (as it truly is). Often, those arguments are theistic arguments, but other non-theistic arguments are also dismissed on the grounds of the same charge.
That view says - "If something is described with human or human-like properties, ie. anthropomorphized, or argued for with arguments containing such anthropomorphizations, then such descriptions or arguments are false, for reality (as it truly is) is not human or human-like."
From the Vedic perspective (and perhaps some others, too), the above view is an example of impersonalism, is it not?
Like all substantial theistic claims, impersonalism has its foundation in scripture. Meaning there are various citations for determining the impersonal aspect of god.
For example the Sanskrit word nirarca can be taken quite literally as no (nir) form (arca)
When there is a statement in the Vedic language that God has no form, it does not mean God has no form, but He has form which one cannot imagine. That is called formless. Actually God is not formless, but the nature of that form, cannot be imagined.
This tallies with other vedic statements which qualify the nature of god’s form, eg
Brahma Samhita 5.31 I worship Govinda, the primeval Lord, whose transcendental form is full of bliss, truth and substantiality and is thus full of the most dazzling splendor. Each of the limbs of that transcendental figure possesses, in Himself, the full-fledged functions of all the organs, and eternally sees, maintains and manifests the infinite universes, both spiritual and mundane.
Sometimes it is indicated how the form of the lord is covered by an impersonal splendour
Iso Mantra 16. O my Lord, O primeval philosopher, maintainer of the universe, O regulating principle, destination of the pure devotees, well-wisher of the progenitors of mankind, please remove the effulgence of Your transcendental rays so that I can see Your form of bliss.
The argument between impersonalists and personalists in the Vedas is not whether the personal/impersonal aspect of god exists or not, but whether it is the personal aspect that is the cause of the impersonal aspect or vice versa.
Anticipating this issue, the BG mentions
BG 7.24 Unintelligent men, who do not know Me perfectly, think that I, the Supreme Personality of Godhead, Kåñëa, was impersonal before and have now assumed this personality. Due to their small knowledge, they do not know My higher nature, which is imperishable and supreme.
And also
BG 12.1 Arjuna inquired: Which are considered to be more perfect, those who are always properly engaged in Your devotional service or those who worship the impersonal Brahman, the unmanifested?
BG 12.2 The Supreme Personality of Godhead said: Those who fix their minds on My personal form and are always engaged in worshiping Me with great and transcendental faith are considered by Me to be most perfect.
And also
BG 14.27 And I am the basis of the impersonal Brahman, which is immortal, imperishable and eternal and is the constitutional position of ultimate happiness.
I recall one incident (
http://www.youtube.com/watch?v=nrP8Dvprrtk&feature=related) where a muslim scholar was arguing against polytheistic ideas in the Vedas by using various impersonal arguments (Islam has strong impersonal threads within its teachings), yet when he came to arguing the validity of the impersonal view on the strength of the Vedas, he cited scriptural references that had given rise to polytheistic practices. In other words one particular natural consequence of impersonalism is a sort of polytheism where any worship of anything you want to call god is as good as any other, since god ultimately has no form, no qualities etc etc.
Anyway … maybe you can see how both views are diametrically opposed despite calling upon various henological arguments to maintain validity
