... and the relentless erosion of idols.
Prayers failed. --> God doesn't exist and religion is bunk.
Justice failed. --> Truth doesn't exist and virtue is bunk.
The experiments failed. --> Nature doesn't exist and science is bunk.
Depending on one's biases, none of the negative aspects of the above dimension of human life will seriously undercut the overarching value and reality of their subjects. Every experiment, to paraphrase T. F. Torrance, is like a prayer to nature, in order to seek if our intentions and actions (hypotheses and experiments) accord with the will of nature. Every legal effort is, or should be, in the pursuit of justice, and even when justice is abused, we must fight that much harder to (literally) rectify things. The power of religion lies in its efforts to bring the inner and out worlds, so to speak, into alignment with the highest reality. The myriad failures in such an endeavor are the fuel for an even greater fire, to be caged only by humility and hope. "[T]he historical development of a science is seldom rational" (J. P. Burgess, _Philosophical Logic_, p. 47). Likewise, the historical development of a religion is seldom spiritual.
