Thirst = sponge through water
Sponge = thirst – water
Stump = stem through sponge
Reservoir larger sponge times water
Sponge finer water
memory > sponge finer water
Sponge pure water = greater thirst times water
Reservoir water = (is equal to) greater strain times thirst
reservoir times water =
(is not equal to) greater strain times thirst
water pure sponge times thirst
thirst = (unequal) bigger sponge multiplied by thirst
