Suspicion always haunts the guilty mind; The thief doth fear each bush an officer.

Suspicion is a virtue as long as its object is the public good, and as long as it stays within proper bounds. ... Guard with jealous attention the public liberty. Suspect every one who approaches that jewel.

Suspicion often creates what it suspects.

Superstition is the child of ignorance and fear.

Educating the mind without morals creates a menace in society.

There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations. It is a thorn that irritates and hurts; it is a sword that kills.

The hysteria of suspicion has made us unreliable to ourselves, trusting neither our aspirations nor our convictions. Suspiciousness, not skepticism, is the beginning of our thinking.

There is nothing so terrible as to live in an atmosphere of suspicion - to see eyes watching you and the love in them changing to fear - nothing so terrible as to suspect those near and dear to you - It is poisonous - a miasma.

No other superstition is so detrimental to growth, so enervating and paralyzing to the minds and hearts of the people, as the superstition of Morality

Conventional opinion is the ruin of our souls.

Pretence about anything sometimes deceives the wisest and shrewdest man, but, however cunningly it is hidden, a child of the meanest capacity feels it and is repelled by it.

The poor man retains the prejudices of his forefathers without their faith, and their ignorance without their virtues; he has adopted the doctrine of self-interest as the rule of his actions, without understanding the science which puts it to use; and his selfishness is no less blind than was formerly his devotedness to others. If society is tranquil, it is not because it is conscious of its strength and its well-being, but because it fears its weakness and its infirmities; a single effort may cost it its life. Everybody feels the evil, but no one has courage or energy enough to seek the cure. The desires, the repinings, the sorrows, and the joys of the present time lead to no visible or permanent result, like the passions of old men, which terminate in impotence.

Weakness, fear, melancholy, together with ignorance, are, therefore, the true sources of Superstition.

The man who believes that the secrets of the world are forever hidden lives in mystery and fear. Superstition will drag him down.
