A gram of experience is worth a ton of theory.

Saturday Review (1859)Robert Cecil
Hold somebody's hand and feel its warmth. Gram per gram, it converts 10 000 times more energy per second that the sun. You find this hard to believe? Here are the numbers: an average human weighs 70 kilograms and consumes about 12 600 kilojoules / day; that makes about 2 millijoules / gram.second, or 2 milliwatts / gram. For the sun it's a miserable 0.2 microjoules / gram.second. Some bacteria, such as the soil bacterium "Azotobacter" convert as much as 10 joules / gram.second, outperforming the sun by a factor 50 million. I am warm because inside each of my body cells there are dozens, hundreds or even thousands of mitochondria that burn the food I eat.
Gottfried Schatz
Experience arises together with theoretical assumptions not before them, and an experience without theory is just as incomprehensible as is (allegedly) a theory without experience.
Paul Karl Feyerabend
Experience by itself teaches nothing...Without theory, experience has no meaning. Without theory, one has no questions to ask. Hence without theory there is no learning.
W. Edwards Deming
The judgment that human life is worth living, or rather can and ought to be made worth living, ... underlies all intellectual effort; it is the a priori of social theory, and its rejection (which is perfectly logical) rejects theory itself.
