Barry Commoner's excellent article can have very far reaching consequences.

The reason that his ideas meet with so much resistance, is that he is coming dangerously close to what is still a tabu subject in scientific thought, namely: that a creative consciousness may well be at work in nature, not only in the distant past (God before the 'big bang’) but in the immediate present; a consciousness that both creates and reads the DNA 'code'. And indeed the disturbing fact that without such a consciousness the very use of the word ‘code’ is irrational, because it unconsciously (and illegitimately) inserts the workings of the human mind into nature, a subject I have dealt with at some length in my book ‘Evolution and the New Gnosis’.  

The tabu I refer to is the one that the English philologist Owen Barfield describes in his book ‘Speaker’s Meaning’ (Wesleyan University Press, Middleton, Conn. 1967), which consists in the text of four lectures that he gave at Brandies University in 1965.  In the fourth lecture the theme of a “great tabu” is introduced and the following two presuppositions are shown to underlie it:  first, that “‘inwardness’ subjectivity of any sort... is always the product of a stimulated organism” and second, that “in the history of the universe... ‘matter’ preceded ‘mind’”. Barfield argues that the requirement that these two presuppositions be strictly observed by scientists, or risk the extreme displeasure of their colleagues, places an irrational limitation on much of modern thought. The tabu, however, applies only to science, because just about all of religion is pre-critical, and can exist today only in a dualism.

I suggest, therefore, that the problems raised by Barry Commomer will not go away until science has learned to overcome this ‘great tabu,’ and then we shall find that the ‘life’ that creates DNA is the same Consciousness that creates and directs the entire natural world.
