Let experience determine.

We are often unable to excite in others the sentiments which we would: words succeed or fail, as they are received or resisted.

But let a scornful expression be addressed to a passionate man, will not the words "call internal feelings" into action?
And how do feelings differ from thoughts ?[29] Hear Dr.James Rush: "The human mind is the place of representation of all the existences of nature which are brought within the scope of the senses.

The representatives are called ideas.

These ideas are the simple passive pictures of things, or [else] they exist with an activity, capable of so affecting the physical organs as to induce us to seek the continuance of that which produces them, or to avoid it.
