Let us cherish sympathy. By attention and exercise it may be improved in every man. It prepares the mind for receiving the impressions of virtue; and without it there can be no true politeness. Nothing is more odious than that insensibility which wraps a man up in himself and his own concerns, and prevents his being moved with either the joys or the sorrows of another.
Upon every hand we meet with those who have some secret resentment that is ever being nurtured within their hearts. They resent the success, or happiness of some one whom they think is less deserving than they are. They resent the just recognition that comes to others from work and long effort to excel. Or, they may resent being born poor - or resent the fact that they were even born!... Strive to excel, strive to achieve, where others have failed, and you will find no space within your mind to lodge resentment. Resentment is the child of selfishness, foolish envy, and inactivity... Our life upon this earth is too valuable for resentment of any kind. There is so much to do, so much to learn - so little time in which to live and work it all out.
Whoever sets out to persuade men to accept a new idea, or one which seems to be new, not just as an idea, but as a truth that is felt, should know beforehand that the human mind is not a blank sheet, on which one an write with ease, and should not therefore grieve or despair when he finds that people do not pay attention to him.
The first real mental illumination I remember to have experienced was when I saw that the universe exists in each of its individual atoms - that is, the universe is the result of a few simple processes infinitely repeated. When a drop of water has been mathematically measured, every principle will have been used which would be called form in the measurement of the heavens. All life on the globe is sustained by digestion and assimilation; when by voluntary and traumatic action these stop death follows. The history of an individual mind is the history of the race. Know one thing in its properties and relations and you will know all things.
It is axiomatic that we should all think of ourselves as being more sensitive than other people because, when we are insensitive in our dealings with others, we cannot be aware of it at the time: conscious insensitivity is a self-contradiction.
[Paraphrase] Self consciousness, while glorious for what is has done, is at the same time baneful, because it precludes man from entering the Cosmic Conscious life, which leads to the infinite - which alone can explain God.
