THREE:Walpole was instantly on the alert on this startling discovery. He prevailed on the king to put off his journey to Germany. Troops were drawn round London and a camp was formed in Hyde Park. The king took up his residence at Kensington, in the midst of the soldiers, and the Prince of Wales retired to Richmond. General Macartney was dispatched for still more troops from Ireland; some suspected persons were arrested in Scotland; the States of Holland were solicited to have ships and soldiers in readiness; an order was obtained from the Court of Madrid to forbid the embarkation of Ormonde; and General Churchill was dispatched to Paris to make all secure with the Regent. Atterbury was arrested on the 24th of August.Meanwhile the strength of the analytical method was doubled by its extension to the phenomena of growth and change; for, as applied to these, it became the famous theory of Development or Evolution. No idea belongs so completely to modern philosophy; for even the ancient thinkers who threw their cosmology into a historical form had never attempted to explain the present by the past. If anything, they explained the past by the present, assuming a rough analogy to exist between the formation of the universe as a whole and the genesis of those natural or artificial bodies which were continually growing or being built up before their eyes. Their cosmology was, in fact, nothing but the old mythology stripped of its personal or conscious element; and, like it, was a hypothesis unsupported by any external evidence;a criticism not inconsistent with the admission that to eliminate the supernatural element from speculation was, even in the absence of any solid addition to human knowledge, an achievement of inestimable value. The evolutionary method is also an elimination of the supernatural, but it is a great deal more. By tracing the history of compound structures to their first origin, and noting the successive increments to which their gradual growth is due, it reveals, as no statical analysis ever could, the actual order of synthesis, and the meaning of the separate constituents by whose joint action their movements are determined; while, conversely, their dissolution supplies us with a number of ready-made experiments in which the influence of each particular factor in the sum total may be detected by watching the changes that ensue on its removal. In a word, the method of evolution is the atomistic method, extended from matter to motion, and viewed under the form of succession instead of under the form of co-existence.
