Paul Henri Thiry D'holbach said this quote

Let education kindle only those which are truly beneficialto the human species; let it favour those alone which are really necessary to the maintenance of society. The passions of man are dangerous, only because every thing conspires to give them an evil direction.

~ Paul Henri Thiry D'holbach

When it shall be desired to enlighten man, let him always have truth laid before him. Instead of kindling his imagination by the idea of those pretended goods that a future state has in reserve for him, let him be solaced, let him be succoured; or, at least, let him be permitted to enjoy the fruit of his labour; let not his substance be ravaged from him by cruel imposts; let him not be discouraged from work, by finding all his labour inadequate to support his existence, let him not be driven into that idleness that will surely lead him on to crime: let him consider his present existence, without carrying his views to that which may attend him after his death: let his industry be excited; let his talents be rewarded; let him be rendered active, laborious, beneficent, and virtuous, in the world he inhabits; let it be shown to him that his actions are capable of having an influence over his fellow men, but not on those imaginary beings located in an ideal world.

~ Paul Henri Thiry D'holbach

It is thus religion infatuates man from his infancy, fills him with vanity and fanaticism: if he has a heated imagination it drives him on to fury; if he has activity, it makes him a madman, who is frequently as cruel to himself, as he is dangerous and incommodious to others: if, on the contrary, he be phlegmatic or of a slothful habit, he becomes melancholy and is useless to society.

~ Paul Henri Thiry D'holbach

If the ignorance of nature gave birth to such a variety of gods, the knowledge of this nature is calculated to destroy them.
