When we discover what our minds actually do, we find out what they have _power_ to do. The _faculties_ of mind are its _powers of acting_ as they are exhibited in our own experience. The following presents a brief outline of the powers and faculties of mind as they have been classified and named by _the people_. _Ideas_ is the word most frequently used to include _all_ the operations and states of mind. Our ideas are often referred to as divided into two classes, viz., ideas gained by the senses, and ideas that pass through the mind without the aid of the senses. Intellectual Powers. The power to gain ideas by the five senses is called _sensation_ or _perception_. The power to have ideas without the use of the senses is called _conception_. _Per_ is the Latin word for _by_, and _con_ is the word for _without_. So we have _per_ceptions _by_ the senses, and _con_ceptions _without_ the senses. _Imagination_ or _fancy_, is the power to make new combinations of our conceptions. _Memory_ is the power of recalling past ideas, and of recognizing them as having existed before. _Judgment_ is the power of comparing ideas, and noticing their relations to each other. _Abstraction_ is the power of noticing certain parts or certain qualities of things, while other parts or qualities are unnoticed. _Association_ is the power of recalling past ideas according to certain modes, called _laws of association_. The above powers are usually classed together, and called _the intellectual powers_, or _the intellect_. The Susceptibilities, or Feelings. The powers of feeling various kinds of pleasure and pain, happiness and misery, enjoyment and discomfort, are called the _susceptibilities_, the _emotions_ and the _feelings_. When any thing is found to be the cause of pleasurable feelings, there follows a desire to secure it, and it is called _good_. When any thing causes pain, a desire follows to avoid it, and it is called _evil_. These _desires_ to secure good and avoid evil are called _motives_ (or movers), because they _move_ the mind to action in order to secure the good desired or to escape the evil feared. The objects that cause such desires are also called motives. For example, _gold_ is called the motive that led a man to murder, and the _desire_ of gold is also called the motive of that act.(4) Desires are measured as _strong_ or _weak_ by our own consciousness. When we desire two incompatible things and must choose one or the other, before the act of choice we are conscious that one creates a desire which is stronger than the other. The only mode of deciding which desire is strongest, is by our own consciousness. The Will. The power of choosing, or willing, is called _the will_. It is also called the power of _volition_. When several desires coexist, some of which must necessarily be denied in order to gratify others, we ordinarily choose that object which excites the strongest desire, as measured by our consciousness.
