POST -KANTIAN IDEALIST SYSTEMS
that
the life of self-expression of this reason could be retraced in
philosophical reflection. They were not nervous men looking over
their shoulders to
see
if critics were whispering
that
they were
producing poetic effusions under the thin disguise of theoretical
philosophy, or
that
their profundity and obscure language were a
mask for lack of clarity of thought.
On the contrary, they were
convinced
that
the human spirit had
at
last come into its own and
that
the nature of reality was
at
last clearly revealed to human
consciousness. And each set out his vision of the Universe with a
splendid confidence in its objective truth.
It
can, of course, hardly be denied
that
German idealism makes
on most people today the impression
of
belonging to another world,
to another climate of thought. And
we
can say
that
the death of
Hegel in
1831
marked the end of an epoch. For
it
was followed
by
the collapse of absolute idealism
l
and the emergence of other lines
of thought. Even metaphysics took a different
tum.
And the
superb confidence in the power and range of speculative philosophy
which was characteristic of Hegel in particular has never been
regained.
But
though German idealism sped through the sky like a
rocket
and
after a comparatively short space of time disintegrated
and fell to earth, its flight was extremely impressive. Whatever
its
shortcomings,
it
represented one of the most sustained
attempts
which the history
of
thought has known to achieve a unified
conceptual mastery of reality and experience as a whole. And even
if the presuppositions of idealism are rejected, the idealist systems
can still retain the power of stimulating the natural impulse of
the
reflective mind to strive after a unified conceptual synthesis.
Some are indeed convinced
that
the elaboration of an overall
view of reality is not the proper task of scientific philosophy. And
even those who
do
not share this conviction
may
well think
that
the achievement 6f a final systematic synthesis lies beyond the
capacity of
anyone
man and is more of an ideal goal
than
a
practical possibility.
But
we
should be prepared to recognize
intellectual stature when
we
meet it. Hegel in particular towers
up
in impressive grandeur above the vast majority of those who have
tried to belittle him. And
we
can always learn from an outstanding
philosopher, even if
it
is only
by
reflecting on our reasons for dis-
agreeing with him. The historical collapse
of
metaphysical idealism
does
not
necessarily entail the conclusion
that
the great idealists

have nothing of value to offer. German idealism has its fantastic
aspects,
but
the writings of the leading idealists are very far from
being all fantasy.
2.
The point which
we
have to consider here is not, however, the
collapse of German idealism
but
its rise. And this indeed stands in
need of some explanation.
On the one hand the immediate philo-
sophical background of the idealist movement was provided
by
the
critical philosophy of Immanuel Kant, who had attacked the claims
of metaphysicians to provide theoretical knowledge of reality.
On
the other hand the German idealists looked on themselves as the
true spiritual successors of
Kant
and
not as simply reacting against
his ideas:
What
we
have to explain, therefore, is how metaphysical
idealism could develop out of the system of a thinker whose name
is for ever
as~ociated
with scepticism about metaphysics' claim to
provide us with theoretical knowledge about reality as a whole or
indeed about
any
reality other
than
the a priori structure of
human knowledge and experience.

The most convenient starting-point for an explanation of the
development of metaphysical idealism out of the critical philosophy
is
the Kantian notion of the thing-in-itseIP
In
Fichte's view
Kant
had placed himself in an impossible position
by
steadfastly
refusing to abandon this notion.
On the one hand, if
Kant
had
asserted the existence of the thing-in-itself as cause
of
the given or
material element in sensation, he would have been guilty of
an
obvious inconsistency.
For
according to his own philosophy the
concept of cause cannot be used to extend our knowledge beyond
the phenomenal sphere.
On the other hand, if
Kant
retained the
idea of the thing-in-itself simply as a problematical
and
limiting
notion, this was
tantamount
to retaining a ghostly relic
of
the very
dogmatism which
it
was the mission of the critical philosophy
to
overcome.
Kant's
Copernican revolution was a great step forward,
and for Fichte there could be no question of moving backwards
to
a pre-Kantian position.
If
one
had
any understanding of the
development of philosophy and of the demands of modem thought,
one could only
go
forward and complete
Kant's
work~
And this
meant eliminating the thing-in-itself. For, given
Kant's
premisses,
there was no room for an unknowable occult
entity
supposed
to
be
independent of mind.
In
other words, the critical philosophy
had
to

philosophy
