Is the pigeon, in whose wing each feather is counted, a mere accident, a mere survival which might have been what it is or something different, or is it something willed and thought, an organic whole? It is the old question whether the idea preceded or followed the reality, on which the whole Middle Ages broke their teeth, the question which separated and still separates philosophers into two camps,—the Realists and the Nominalists. I think that the latest investigations show us that the Greek philosophers, and especially Plato, saw more correctly when they recognised behind the multiplicity of individuals the unity of the idea, or the species, and then sought the true sequence of evolution not in this world, in a struggle for existence, but beyond the perception of the senses, in a development of the Logos or the idea. The circumstances, it appears to me, in this view remain just the same; the sequence, and the purposiveness in this sequence, remain untouched, only that the Greeks saw in the rational and purposive in nature the realisation of rational progressive thoughts, not the bloody survivals of a monstrous gladiatorial combat in nature. The Darwinians appear to me to resemble the Roman emperors, who waited till the combat was ended, and then applauded the survival of the fittest. The idealist philosophy, be it Plato’s or Hegel’s, recognises in what actually is, the rational, the realisation of eternal, rational ideas. This realisation, or the process of what we call creation, can never be conceived by us otherwise than figuratively. But we can make this figurative presentation clearer and clearer. That the world was made by a wood cutter, as was originally implied in the Hebrew word _bara_, and in the German _schoepfer_, _schaffer_, in the English _shaper_, or in the Vedic _tvashtâ_, and the Greek τέκτων, was quite comprehensible at a time in which man’s highest product was that of the carpenter and the stone mason; and in which the name of timber (_materies_) could become the universal name for matter (ὕλη, wood). After this idea of the founder of the universe as a carpenter or builder was abandoned as inadequate, the world was divided into two parties. The one adopted the theory of material primitive elements, whether they be called atoms, or monads, or cells, which by collision or struggle with each other, and by mutual affinity, became that which we now see around us. The other saw the impossibility of the rise of something rational out of the irrational, and conceived a rational being, in which was developed the original type of everything produced, the so-called Logos of the universe. How this Logos became objectively and materially real, is as far beyond human comprehension as is the origin of the cosmos out of countless atoms, or even out of living cells. So far, then, one hypothesis would be as complete and as incomplete as the other. But the Logos hypothesis has the
