There is certainly some remedy; nor has nature been so unkind to the human race as to have discovered so many things salutary to the body, and none which are medicinal to the mind.

She has even been kinder to the mind than to the body; inasmuch as you must seek abroad for the assistance which the body requires, while the mind has all that it requires within itself.

But in proportion as the excellency of the mind is of a higher and more divine nature, the more diligence does it require; and therefore reason, when it is well applied, discovers what is best, but when it is neglected, it becomes involved in many errors.

I shall apply, then, all my discourse to you; for though you pretend to be inquiring about the wise man, your inquiry may possibly be about yourself.

Various, then, are the cures of those perturbations which I have expounded, for every disorder is not to be appeased the same way.
