Thus, the same sensibilities continue to characterize the various parts of my organism.

Similarly, there are the higher intellectual, emotional, and moral peculiarities and dispositions.

My idea of my persistent self is essentially a collective image representing a relatively unchanging material object, endowed with unchanging sensibilities and forming a kind of support for permanent higher mental attributes.
The construction of this idea of an enduring unchanging ego is rendered very much easier by the fact that certain concrete feelings are approximately constant elements in our mental life.

Among these must be ranked first that dimly discriminated mass of organic sensation which in average states of health is fairly constant, and which stands in sharp contrast to the fluctuating external sensations.

These feelings enter into and profoundly colour each person's mental image of himself.
