realizing the life

Example 1:
If a person never got a shock from electricity, we'll not be able to explain
the experience or feeling of being hurt by current shock. We can only give
some hints but he'll never be able to know "what exactly electric shock is"?
unless he experiences shock himself.

Example 2:
You smelled a fragrance of flower and trying to explain its fragrance to a
friend who has never smelled it. Again hints will not be able to explain the
nature of that fresh completely.

Example 3:
Suppose a person has never seen a transparent glass. He'll never be able to
understand the concept of transparency unless he witnesses the glass himself.

There can be many more to show that logics alone can never completely
satisfy us.
This is the primary fault with most of atheists and agnostics. They use their
logics without using will - You may guess now how many vital experiences
an atheist misses just because of a shit named as "ego".
