ground-rent and the undertaker's profit, I was prevented by this
fundamental error from arriving at satisfactory views concerning the
constitution and character of the future forms of organisation based upon
the principle of free organisation. _That_ and _wherefore_ economic freedom
and justice must eventually be practically realised, I had shown; on the
other hand, _how_ this phase of evolution was to be brought about I was not
able to make fully clear. Yet I did not ascribe this inability to any error
of mine in thinking the subject out, but believed it to reside in the
nature of the subject itself. I reasoned that institutions the practical
shaping of which belongs to the future could not be known in detail before
they were evolved. Just as those former generations, which knew nothing of
the modern joint-stock company, could not possibly form an exact and
perfect idea of the nature and working of this institution even if they had
conceived the principle upon which it is based, so I held it to be
impossible to-day to possess a clear and connected idea of those future
economic forms which cannot be evolved until the principle of the free
association of labour has found its practical realisation.

I was slow in discovering the above-mentioned connection of my doctrine of
social evolution with the orthodox system of economy. The most
clear-sighted minds of three centuries have been at work upon that system;
and if a new doctrine is to win acceptance, it is absolutely necessary that
its propounder should not merely refute the old doctrine and expose its
errors, but should trace back and lay open to its remotest source the
particular process of thought which led these heroes of our science into
their errors. It is not enough to show _that_ and _wherefore_ their theses
were false; it must also be made clear _how_ and _wherefore_ those thinkers
arrived at their false theses, what it was that forced them--despite all
their sagacity--to hold such theses as correct though they are simply
absurd when viewed in the light of truth. I pondered in vain over this
