Do you smoke?
Is it healthy?
Did you get vaccinated?
Seeing is believing
We see, we hear, we have an Empirical Truth

We perceive the world with our 8 senses
We can have optical illusions

Google “The Dress”, and watch “The Dress is Bloie”
Put one hand in hot water, the other in cold water
Then put both in warm water
Is it hot or cold?
Have you ever seen someone that was not there?
and we don’t know that we are dreaming
feeling as if one has lived this moment before
See, for instance
Michaelian Kourken “Confabulating, Misremembering, Relearning: The Simulation Theory of Memory and Unsuccessful Remembering”. Frontiers in Psychology 7 (2016) DOI 10.3389/fpsyg.2016.01857

We forget, and we forget that we forget
Our experience is limited
At our scale
Our friends are like us. It seems that everybody agrees with us
We only see our neighborhood of the network, where everybody looks like us

“The body is dirty,
the soul is pure”
That will be tomorrow’s class

What can we do to see if the Earth rotates on it axis?
