A 'good path' to be understood through the lens of Alexander's 'good shape' property; at first this was NON-FREE MOVEMENT THROUGH A SPACE, but it is not about freedom or a lack of freedom at all. Your movement through a space is a line of flow through a work, it is part of the composition. If you beeline through a garden then, no matter how beautiful or lush the garden, there is nothing interesting about that element of the composition.
