When reading various scholars attempts to engage with the difficult subject of technological determinism, I've collected the following analytical variables with which they contend. I've also attempted to integrate them into a metaphor of a man trying to move a large stone.

Momentum

The rock is rolling north

Intent

The rock will be used in a wall

Contingency

The rock will get stuck in a groove

Lifecycle

Dimensions

The rock flattens the grass, erodes the soil, leaves a hole but contributes to a wall

Directness

The rock tends to the left

Agency

The person is a serf without much choice
