From what I can tell, these attitudes largely progressed through three phases. 4. 5. 7. 6.
These attitudes cannot be attributed to space alone.
( z0 possible :ARG1 ( z1 attribute :ARG1 ( z2 attitude :mod ( z3 this ) ) :ARG2 ( z4 space :mod ( z5 alone ) ) ) :polarity - )
(z0 / possible-01
    :ARG1 (z1 / attribute-01
              :ARG1 (z2 / attitude
                        :mod (z3 / this))
              :ARG2 (z4 / space
                        :mod (z5 / alone)))
    :polarity -)
These attitudes cannot be attributed to space alone .
z2 :mod z3
z0 :polarity 0
z0 :ARG1 z1
z1 :ARG1 z2
z1 :ARG2 z4
z4 :mod z5
