When you are able by methodical and repeated effort to objectivise and keep at a distance all this flood of incoherent thoughts which assail us, you will notice a new phenomenon.
You will observe within yourself certain thoughts that are stronger and more tenacious than others, thoughts concerning social usages, customs, moral rules and even general laws that govern earth and man.
They are your opinions on these subjects or at least those you profess and by which you try to act.
Look at one of these ideas, the one most familiar to you, look at it very carefully, concentrate, reflect in all sincerity, if possible leaving aside all bliss, and ask yourself why you have this option on that subject rather than any other.
The answer will almost invariably be the same, or nearly:
Because it is the opinion prevalent in your environment, because it is considered good form to have it and therefore saves you from as many clashes, frictions, criticisms as possible.
Or because this was the opinion of your father or mother, the opinion which moulded your childhood.
Or else because this opinion is the normal outcome of the education, religious or otherwise, you received in your youth. This thought is not your own thought.
For, to be your own thought, it would have to form part of a logical synthesis you had elaborated in the course of your existence, either by observation, experience and deduction, or by deep, abstract meditation and contemplation.
