Quote from ‘On the System of Existential Graphs Considered as an Instrument for the Investigation of Logic’
The first mode of separating one constituent of the phaneron from another consists in imagining a state of things as to which the one may be affirmed while the other is denied. Thus we may imagine that there are brilliant colors while there are no sounds whatever, or the reverse. I called this mode of analysis dissociation.
