1. We have five senses: seeing, hearing, feeling, tasting, and smelling.
When we see, feel, taste, or smell things, or hear sounds, we are said to perceive them.
If I drop a book upon the floor. Nature draws it down, through the air, to the ground. We can not perceive this force, but we are conscious of it,—that is, we know such a force must exist. We are conscious of many other things that we can not perceive; as, love, hatred, joy, sorrow. All these things that exist in Nature are called “objects”. What, then, is an object?
2. An Object is any thing we can perceive, or of which we may be conscious.
When we perceive or are conscious of any thing, we form an image of that object in our minds. These images are called ideas. What, then, is an idea?
3. An Idea is a mental image of an object we perceive or are conscious of.
When we think, we think of objects; when we speak, we speak of ideas; when we write, we write of ideas. When we speak or write, we use words to express our ideas. What, then, is a word?
4. A Word is a syllable, or a combination of syllables, used to signify an idea.
