Who is the observer?

Isn´t it strange?… Is it possible to observe the present moment, with a totally unbiased frame of mind?…

The moment we see something, observe something…- it feels as if it´s not we observing, but our past with its notions, habits, preferences.

Who is the observed? And who´s actually this observer? Do we know anything about him?

As this observer abides in the past, being the result of our experience and conditioning, how can we ever rely on his perception?

My question is:

Is there a way to grasp this very Now without memory, without thought and preconception?
