Goodness of God in annexing pleasure and pain to our other ideas.
Though what I have here said may not, perhaps, make the ideas of pleasure and pain clearer to us than our own experience does, which is the only way that we are capable of having them; yet the consideration of the reason why they are annexed to so many other ideas, serving to give us due sentiments of the wisdom and goodness of the Sovereign Disposer of all things, may not be unsuitable to the main end of these inquiries: the knowledge and veneration of him being the chief end of all our thoughts, and the proper business of all understandings.

Ideas of Existence and Unity.
EXISTENCE and UNITY are two other ideas that are suggested to the understanding by every object without, and every idea within.

When ideas are in our minds, we consider them as being actually there, as well as we consider things to be actually without us;--which is, that they exist, or have existence.

And whatever we can consider as one thing, whether a real being or idea, suggests to the understanding the idea of unity.

Idea of Power.
POWER also is another of those simple ideas which we receive from sensation and reflection.
