II. Desires, which follow from our nature in such a manner, that they can be understood through it alone, are those which are referred to the mind, in so far as the latter is conceived to consist of adequate ideas: the remaining desires are only referred to the mind, in so far as it conceives things inadequately, and their force and increase are generally defined not by the power of man, but by the power of things external to us: wherefore the former are rightly called actions, the latter passions, for the former always indicate our power, the latter, on the other hand, show our infirmity and fragmentary knowledge.
III. Our actions, that is, those desires which are defined by man's power or reason, are always good. The rest may be either good or bad.
IV. Thus in life it is before all things useful to perfect the understanding, or reason, as far as we can, and in this alone man's highest happiness or blessedness consists, indeed blessedness is nothing else but the contentment of spirit, which arises from the intuitive knowledge of God: now, to perfect the understanding is nothing else but to understand God, God's attributes, and the actions which follow from the necessity of his nature. Wherefore of a man, who is led by reason, the ultimate aim or highest desire, whereby he seeks to govern all his fellows, is that whereby he is brought to the adequate conception of himself and of all things within the scope of his intelligence.
V. Therefore, without intelligence there is not rational life: and things are only good, in so far as they aid man in his enjoyment of the intellectual life, which is defined by intelligence. Contrariwise, whatsoever things hinder man's perfecting of his reason, and capability to enjoy the rational life, are alone called evil.
VI. As all things whereof man is the efficient cause are necessarily good, no evil can befall man except through external causes; namely, by virtue of man being a part of universal nature, whose laws human nature is compelled to obey, and to conform to in almost infinite ways.
VII. It is impossible, that man should not be a part of nature, or that he should not follow her general order; but if he be thrown among individuals whose nature is in harmony with his own, his power of action will thereby be aided and fostered, whereas, if he be thrown among such as are but very little in harmony with his nature, he will hardly be able to accommodate himself to them without undergoing a great change himself.
