Spatial in that

Spatial in that they have no spatial dimensions, and thus no orientation in space, nor do they even (like the point)   closely related with the complete reducibility semi simplicity of their representations. When the ground field F has characteristic zero, any finite-dimensional representation of a semi simple Lie algebra is semi simple  individuals with particular traits to determine the character of the person and thus many phrenology books have many pictures.
