Non-static method Pages::view() cannot be called statically

This is what my code looks like

PHP Code:

class Pages extends CI_Controller {   
    public function view($page = 'home'){
        if ( ! file_exists(APPPATH.'views/pages/'.$page.'.php'))
        {
            // Whoops, we don't have a page for that!
            show_404();
        }
 
        $data['title'] = ucfirst($page);
        $data['description'] = "Description";
        $data['keywords'] = "Keywords";
        $data['page'] = 'pages/'.$page;
        $this->load->view('templates/template', $data);
    }
}
