The apeiron has no qualities because:

a. Anaximander was clever, and didn't want to be proven incorrect

b. Qualities were paradoxical, and so he eliminated them from metaphysics.

c. He needed to resolve the problem of opposing forces, that Thales' philosophy faced.

c. He needed to resolve the problem of opposing forces, that Thales' philosophy faced.

Explanation:

Apeiron which is a Greek word and literally means, boundless, infinite or limitless.

According to Anaximander, one of the Greek philosopher, in trying to explain the apeiron, he suggested that, apeiron which is infinite in nature, can not be restricted by having qualities that can be opposed, as Thale philosophy tried to attributes apeiron to Infinite source which he described as Water.

However, Anaximander believed that, Water has opposing force in fire, which is a problem to the philosophy of Thale.

Hence, Anaximander suggested that apeiron has no qualities or form, and cannot be either Water, or Fire.

C. He needed to resolve the problem of opposing forces, that Thales' philosophy faced.

Explanation:

"Apeiron" in Greek refers something that can't be bounded, and is infinite or limitless.

Anaximander, a Greek philosopher, and one of the disciples of Thales in his attempts to explain the apeiron, indicated that, apeiron that is infinite in nature, is impossible to be limited within the qualities that it can be opposed, with Thale philosophy trying to attribute apeiron to Infinite source that he described using Water. Thales held that everything in the world and the origin of the world had come through water--an explanation based on the discovery of fossil sea animals far inland

Anaximander on the other hand believed Water has an opposing force "in fire", He considered this to be a problem to the philosophy of Thale which suggested apeiron has infinite source described through water.

Anaximander then implied that apeiron has no qualities neither does it have form, and that apeiron cannot be either of Water, or Fire.
