Now this is a perfectly valid criticism on all such previous non-theistical arguments as were drawn from an "indication of the process by which the order has been realised;" for in all these previous arguments there was an absence of any physical explanation of the ultimate cause of the process contemplated, and so long as this ultimate cause remained obscure, although the evidence of design might by these arguments have been excluded from particular processes, the evidence of design could not be similarly excluded from the ultimate cause of these processes.
