On the fraud
To know if a man is a fraud, see if he teaches you one thing and does another.
A fraud says one thing and does another: He turns his own words into lies.
The writer is his writings: The aphorist, his aphorisms; the poet, his poems; the novelist, his novels; and the essayist, his essays. But not always: There are some frauds in my library.
You know a fraud: Not just by looking at the books, but also by looking at the writer (he is not his writings).
A philosopher is the wisdom that he sees and shows others, never a fraud.
To know if a philosopher is a fraud, see if he is not the wisdom that he sees and shows others.
Do not just philosophize; practice the wisdom that you see.
As I read in a history book, they told Lucius Annaeus Seneca that he turned his philosophy into lies by not practicing it himself.
Emil Cioran: Arthur Schopenhauer, Jean-Jacques Rousseau and Friedrich Nietzsche turn their opinions into lies by not living them.
Do not turn your advices (and the wisdom behind them) into lies by not keeping them yourself.
You are either a fraud in some, or in all, or in nothing.
Be your own philosophy; always.
 A fraud is like a liar; a fraud is like a man who does not keep his promises or his oath.

 Nassim Taleb is a role model in reverse: For him, the coronavirus pandemic was (and it still is) an opportunity to philosophize; but he did not practice his own philosophy and, as he said, was the only one who got infected with COVID-19 during a party. Taleb is not the wisdom he shows others; he is a fraud.
For Nassim Taleb, If you see a fraud and do not shout fraud, you are a fraud.
 Emil Cioran, too, is a fraud, given that he is not the opinions that he expressed in Le Mauvais Démiurge, at least, as he said in Cahiers.
