Question

Explain"all knowledge starts from senses"?

Answer 1

"Consciousness with nothing to be conscious of is a contradiction in terms." Ayn Rand from Aristotle

But consciousness is tabula rasa. The trauma of birth is that the infant is suddenly confronted by all of his senses at the same time, including a doctor or nurse expunging the fluids from the infants mouth.

This begins the process of filling the tabula rasa. The hard-wired faculty of epistemology begins to work on those new senses, trying to figure them out.

Occasionally a child is born with no sensory ability. That child is dead within hours.

Answer 2

This is just a short summing-up of an extreme form of empiricism.  Rather than admitting that there is actually something hard-wired in the brain - which is actually the case - empiricists say that all knowledge is derived from the senses.
