Empirical evidence is a way of describing knowledge obtained through an experiment. Strictly speaking, an experiment should have a hypothesis, a manipulation of a single variable, observations, and a conclusion drawn based on those observations.
Is it just some way of labeling life experience?
I believe that some life experiences could be considered empirical evidence. For example, suppose you go on three separate dates with three separate guys. One dates one and two, you wear a push-up bra. On date three, you do not. Suppose the gentlemen from dates one and two both call for another date, and the gentleman from date three did not. You could then deduce a trend suggesting that push-up bras lead to second dates.
Is there merit to it?
You tell me. Would you rather take a pill that had been tested during clinical trials to treat a medical condition you had, or would you rather take your chances and choose any pill at random?
Is it worth considering despite its avoidance of the scientific method?
I believe this fundamentally misunderstands the meaning of the word “empirical.” It categorically does not avoid the scientific method. I do not believe there is any commonly used definition, colloquial or formal, that separates empirical thought from scientific thought.
How would you sum up in a paragraph all of the empirical evidence that has brought you to where you are right this minute with regards to your beliefs (or lack thereof)?
Are you referring specifically to religious beliefs? We can do a nice little experiment right now.
Dear God,
If you exist, please bring me candy in the next ten seconds.
(One, two, three, four, five, six, seven, eight, nine, ten.)
Who thinks I have candy right now?
