Meditations 10.12

What need is there of suspicious fear, since it is in thy power to inquire what ought to be done? And if thou seest clear, go by this way content, without turning back: but if thou dost not see clear, stop and take the best advisers. But if any other things oppose thee, go on according to thy powers with due consideration, keeping to that which appears to be just. For it is best to reach this object, and if thou dost fail, let thy failure be in attempting this. He who follows reason in all things is both tranquil and active at the same time, and also cheerful and collected.
