indeterminate, undeveloped self-existence,
capable, indeed,
of becoming a definite reality, but not
yet made into one. By Actuality, on the other hand,
he means the same being considered as a developed
totality or Being which has wrought out all that it
contains into full existence. When accordingly he
identifies Form with actual, Matter with potential,
being, he means to say that the former is the totality
of the qualities which the latter does not possess but
is capable of acquiring. 1 Matter as such, the so-called

j ust that which precedes all Becoming and all
formation
the centre of indifference to all opposites and definite
qualities ; the substratum which as yet possesses
none of the qualities that make the Form of things. 3
